Question

A cylinder has a volume of 8792 cubic units. If the height is 7 cubic u it’s which of the following is the radius

Answer 1

20 units

Explanation:

Volume of a cylinder = πr²h

V = πr²h

height, h = 7

V = π * r² * 7

V = 8792

8792 = 21.991148 * r²

r² = 8792 / 21.991148

r² = 399.79722

r = √399.79722

r = 19.99unit

r = 20 units
