The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.
<h3>What is the Lateral Surface Area of a Cone and a Cylinder?</h3>
Lateral surface area of cone = πrl
Lateral surface area of cylinder = 2πrh
Lateral surface area of cone A = πrl = πrh
Lateral surface area of cylinder B = 2πrh
This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.
The answer is: A. True.

X = 38
2x is equal to the angle next to the x + 66 angle because ℓ1 ∥ ℓ2 is parallel so:
2x + x + 66 = 180 -- combine like terms
3x + 66 = 180 -- subtract 66 from both sides
3x = 114 -- divide by 3 on both side
x = 38
The mean is the average. Add all the numbers together, then divide by the quantity of numbers in the data set.
1040 / 13 = 80
The mean is 80
