The approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches
What is the lateral area of cone?Lateral area of the cone is the area bounded by the surface of the cone, and this Lateral area of the cone can be found out using the following formula.
[tex]A=\pi r\sqrt{h^2+r^2}[/tex]
here. (h) is the height of the cone and (r) is the radius of the cone.
A cone has a circular base with a diameter of 18 inches. The height of the cone is 40 inches.
Put these values in the above formula as,
[tex]A=(3.14) (9)\sqrt{40^2+9^2}\\A\approx1159\rm \; in^2[/tex]
Hence, the approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches

Answer: m<D = 30
Step-by-step explanation: In the third step of the problem, it says that E is next to itself and equals 90. However, this is not true. Angle BEA and angle CED are vertical angles and are both equal to 65°. This means that to find the measurement of angle D, subtract 65 and 85 from 180, which equals 30.

The shaded part of the circle below represents the portion of a garden where a landscaper planted rose bushes. What is the approximate area of the part of the garden used for rose bushes?
Answer:
942ft^2
Step-by-step explanation:
Use the equation (θ/360)*[tex]\pi[/tex][tex]r^{2}[/tex] to get the area of the shaded sector.
(120/360)*[tex]\pi[/tex]*[tex]30^{2}[/tex]

≈942[tex]ft^{2}[/tex]
The area of the shaded region is 942 square ft if the radius of the circle is 30 ft option (G) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle shown in the picture.
The area of the shaded region:
[tex]\rm A = \dfrac{120}{360}\pi (30)^2[/tex]
A = 942.47 ≈ 942 square ft

2. Given A=15°, b=8, and a=6, use the Law of Sines to solve the triangle (if possible)
for the value of c. If two solutions exist, find both. Round answer to two decimal places.
A) c=11.01
B) c=2.10 and 13.36
C) c=12.14
D= c=1.12 and 10.24
E) not possible
Answer:
B
Step-by-step explanation:
The Law of Sines states that
sinA/a = sinB/b = sinC/c
We know A, a, and b. Given this, we can solve for B, and given that, we can solve for C and then c.
First, we solve for B.
sinA/a = sinB/b
sin(15°)/6 = sinB/8
sin(15°)/6 * 8 = sinB
arcsin(sin(15°)/6 * 8) = B ≈ 20.187
Note that there can be a second B value. We can check if there is a second B value by first subtracting the B value we got from 180.
180 - 20.187 = 159.813
Next, we can add that to our existing angle, A = 15°. If that is less than 180, then we do have a second solution. 159.813 + 15 = 174.813 < 180 so there does exist a second solution where B = 159.813
Next, we can solve for C.
We know that the angles in a triangle add to 180°, so A + B + C = 180. Therefore, for the first solution:
15 + 20.187 + C = 180
C = 180 - 15 - 20.187 = 144.813°
and for the second:
15 + 159.813 + C = 180
C = 180 - 15 - 159.813 = 5.187
Finally,
sinA/a = sinC/c
multiply both sides by c to no longer have it as a denominator
sinA * c / a = sinC
divide both sides by (sinA/a) to isolate c
for the first solution:
c = sinC*a/sinA = 13.35868 ≈ 13.36
and for the second:
c = sinC*a/sinA ≈ 2.10

Explanation:
One method is to do the steps like this
15% of 60 = 0.15*60 = 9
Or you can solve like this
part/whole = percent/100
x/60 = 15/100
100x = 60*15
100x = 900
x = 900/100
x = 9
Write the fraction as a percent.

The radius of a circle is 16 millimeters. What is the circle's area?
Use 3.14 for .
please answer windowesssssssssssssss
Answer:
803.84 millimeters²
Step-by-step explanation:
How do we find the area of a circle?
The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.Solving
[tex]3.14 *16^2[/tex] [tex]3.14*256[/tex] [tex]803.84[/tex]Therefore, the area is 803.84 square millimeters.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Solution:
We know that:
Radius = r = 16 mmArea of circle = (π)(r²)Finding the area of the circle:
Area of circle = (3.14)(16²)=> Area of circle = 3.14 x 16²=> Area of circle = 3.14 x 256=> Area of circle = 803.84 mm²William has scored a total of 235 points on the first three math tests taken in his mathematics class. If his mathematics test are always worth 100 points, how many points must he earn on his next test in order to have an average of 80%
Answer:
85 points
Step-by-step explanation:
His total points will be 235+x
Number of tests will be 4
(235+x)/4 = 80
multiply by 4
235+x= 4*80
235+x= 320
x=320-235
x= 85
He has to get 85 points to average 80
Find the measure of the missing angles .
Answer:
x = 29°, y = 61°
Step-by-step explanation:
x + 61 = 90
Because of the right angle symbol
x = 90 - 61
x = 29°
x + y = 90
Because vertically opposite angles are equal
29 + y = 90
y = 90 - 29
y = 61°
