Answer 1

V = 707 cubic feet

Explanation:

The volume of a cylinder

V = πr^2h

V - volume of a cylinder

π - pie

r - radius of the cylinder

h - height of a cylinder

Given

d - 10ft

h - 9ft

π - 3.14

Insert the value into the formula

Given diameter

d = 10ft

d = 2r

r = d/2

r = 10/2

r = 5ft

V = 3.14 × 5^2 ×9

= 3.14 × 25 × 9

= 706.5 cubic feet

To nearest whole number

V = 707 cubic feet
