Formula: [tex]\frac{4}{3}\pi r^3[/tex]
Plug in values: radius = 9.3
Volume: 1072.476π cubic units
Step-by-step explanation:
The formula to find the volume of a sphere is [tex]\frac{4}{3}\pi r^3[/tex], where r = radius. In this case, we leave the volume of sphere in terms of pi.
The only value we can plug in is the radius. In this case, the radius is 9.3 units.Now, we can solve for the volume:
[tex]\frac{4}{3} *9.3^3 * \pi[/tex] [tex]\frac{4}{3} * 804.357 * \pi[/tex] [tex]1072.476 * \pi[/tex] [tex]1072.476\pi[/tex]Related Questions

Answers
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]
Write the equation of a line in slope intercept
form of a line that has a slope of 2/3 and contains (-6,3)
Answers
Answer: y = (2/3)x + 7
Step-by-step explanation:
Slope intercept form is usually write as y = mx + b, where m is the slope, b is the y-intercept.
(-6,3): -6 is the x, 3 is the y.
To solve b, we plug in x, y and m into the equation:
y = mx + b
3 = (2/3)(-6) + b
3 = -4 + b
7 = b
Then we plug m and b in, we get:
y = mx + b
y = (2/3)x + 7

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
Answers
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 is a bond interest rate?The bond interest rate is the annual interest (coupon) rate paid on a bond.
The amount of interest is expressed as a percentage of the face value.
The bond interest (rate or amount) represents the periodic compensation that is due in exchange for the bondholder's agreement to lend their funds to the entity for some period.

What is the number of years it will take the investment to double? if Moe invests $ 7,500 in an account that pays 2.4% interest compounded monthly. Round your final answer to two decimal places.
Answers
Answer:
28.91 years
Step-by-step explanation:
The investment value is multiplied each year by the factor ...
(1 +r/12)^12
= (1 +0.024/12)^12 = 1.002^12 ≈ 1.024265768
When the investment is multiplied by this factor for x years, the multiplication factor becomes 1.024265768^x. We want to know the value of x that makes this equal to 2:
2 = 1.024265768^x
log(2) = x·log(1.024265768) . . . . . take logarithms
x = log(2)/log(1.024265768) ≈ 28.91
It will take 28.91 years for the investment to double at 2.4% compounded monthly.

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
