Question

What is volume of a cylinder with base area 64πcm2 and a height equal to twice the radius? Give your answer in terms of π

Answer 1

1024π

Explanation:

Took a quiz, got this answer right.

Here are the steps anyways:

64π cm² is the base area

The height is equal to twice the radius

Volume of a Cylinder: V=B×h/V=πr²×h

1. Find radius: √64 (Which is 8)

2. Double the radius, 8×2=16

3. Multiply 16 and 64π, 16×64π=1024π

hopefully this was understandable, first time answering a question
