A circle has a diameter of 28 centimeters.
Estimate the area of the circle. Use
3.14
or
22
___
7
for
π
.
Answer:
616 square centimeters
Step-by-step explanation:
Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.
Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.
Multiply 14 squared by 22/7:
(22/7)(14^2)
This gives us (22/7)(196); (4312/7); 616.
Therefore, the area of the circle is approximately 616 square centimeters.
A tube of tennis balls has the following measures: 4-inch diameter and a height of 8 inches. What is the surface area of the tube of tennis balls? (Use 3.14 for π.)
A)301.44 in.^ 2
B)226.08 in. ^2
C)213.52 in. ^2
D)125.6 in. ^2
The surface area of the tube of tennis balls is 125.6 inches
What is the surface area of the tube of tennis balls?The given parameters are:
Diameter, d = 4 inches
Height = 8 inches
Start by calculating the radius (r)
Radius (r) = Diameter/2
So, we have
r = 4 inches/2
Evaluate
r = 2 inches
The surface area of the tube of tennis balls is calculated as:
Surface area = 2πr(r + h)
So, we have:
Surface area = 2 * 3.14 * 2 * (2 + 8)
Evaluate the product
Surface area = 125.6 inches
Hence, the surface area of the tube of tennis balls is 125.6 inches

The inequality x< 30 can be used to represent how tall a tree is, where x is its height in feet. Write a statement that best describes how tall the tree is?
Answer:
The tree is shorter than 30 feet.
Step-by-step explanation:
The expression x<30 shows that the height of the tree is less than 30 so we can say that the tree's height is less than 30 feet.

In a game, each participant has to carry water with a small hemispherical container of radius 3 cm, and then pour the water into a larger hemispherical bowl of radius 9 cm. Find the least number of times a participant must carry water so that the larger bowl is fully filled.
Answer:
81 times
Step-by-step explanation:
The problem is essentially asking for the volume of the two hemispheres. Once the volume of the two hemispheres are found, we can divide the larger hemisphere by the smaller one. That will give the amount of times the smaller volume fits into the larger volume.
The volume of a hemisphere is the volume of a sphere divided by 2. Therefore, the volume of the smaller hemisphere is:
[tex]v = \frac{1}{2} (\frac{4}{3} \pi {r}^{3} )[/tex]
[tex]v= \frac{1}{2} (\frac{4}{3} \pi {3}^{3} )[/tex]
[tex]v = 6\pi[/tex]
The volme of the larger hemisphere is:
[tex]v = \frac{1}{2} ( \frac{4}{3} \pi {9}^{3} )[/tex]
[tex]v = 486\pi[/tex]
Then:
[tex] \frac{486\pi}{6\pi} = 81[/tex]

PLEASE HELP ME!!!!!!!!!!! VE ()) You roll a 6-sided die two times. 1) What is the probability of rolling a number greater than 3 and then rolling a number greater than 3? ()) Write your answer as a percentage. % Submit
Answer:
25%
Step-by-step explanation:
Ok, so a die is rolled twice. The probability of rolling a number greater than three is 3/6 or 1/2 because 4, 5, and 6 are greater than three.
The probability of rolling a number greater than three the second time is also 3/6 or 1/2.
To get the answer of rolling both greater than three in a row, you simply multiply then together:
1/2 * 1/2= 1/4 So there is 1/4 chance or probability a number greater than 3 would be rolled twice in a row.
1/4 is the same as 25%

-What applications do real numbers have in our daily lives?
2. Make a summary (one page) of your search and what you learned in APA style format
In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line. The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary roots of polynomials.
In addition to measuring distance, real numbers can be used to measure quantities such as time, mass, energy, velocity, and many more. Real numbers can be thought of as points on an infinitely long line called the number line or real line, where the points corresponding to integers are equally spaced

Kiana's soccer team's ratio of wins to losses is 5:3. Her team has played 24 games. How many games have they won?
The win-to-loss ratio of 5:3 is a "part-to-part" ratio, so we can represent each part as a fraction of the whole. We can do this by simply adding 3 + 5 = 8 (the "whole") and dividing by that total. This gives us a ratio of Images, which means that the Bombers won Images of their games and lost Images of them. Since they played a total of 120 games, they won Images games and lost Images games.
we know the team has played a total of 24, and we know the wins : losses ratio is 5 : 3, so let's simply divide 24 by (5 + 3) and distribute accordingly.
[tex]\cfrac{wins}{losses}\implies \cfrac{~~5\cdot \frac{24}{5+3}~~}{3\cdot \frac{24}{5+3}}\implies \cfrac{~~ 5\cdot \frac{24}{8}~~}{3\cdot \frac{24}{8}}\implies \cfrac{5\cdot 3}{3\cdot 3}\implies \cfrac{\stackrel{\mathbb{WINS}}{15}}{9}[/tex]

equilateral triangle MNQ inscribed in circle C
equilateral triangle ANP inscribed in circle C
regular hexagon AMNBPQ inscribed in circle C
square MNPQ inscribed in circle C
square ANBQ inscribed in circle C
Answer: equilateral triangle ANP inscribed in circle C, regular hexagon AMNBPQ inscribed in circle C
Step-by-step explanation:
By looking through our choices, we can eliminate which choices could be wrong and which choices could be right.
Δ MNQ does form a triangle, however, it DOES NOT form a equilateral triangle.
Δ ANP does form a triangle and it is ALSO an equilateral triangle.
Hexagon AMNBPQ does form a hexagon and it is ALSO a regular polygon as we can see all the sides and angles within the polygon are congruent to one another.
MNPQ does form a quadrilateral, however, it DOES NOT form a square. It is instead a rectangle.
ANBQ does form a quadrilateral, however, it DOES NOT form a square. It is instead a rectangle.
