Question

What is the volume of a cylinder, in cubic feet, with a height of 8 feet and a base

Answer 1

Answer:

see below

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter is 18 so the radius is 1/2 d = 1/2(18) = 9

V = pi (9)^2 (8)

V =648 pi

Letting pi = 3.14

V = 648(3.14)

V =2034.72

Rounding to the tenths place

V =2034.7 ft^3

If you use the pi button

V = 2035.75204

Rounding to the tenths place

V =2035.8

Answer 2

Answer:

2034.7

Step-by-step explanation:

Since we know V = 3.14 * r * r * h

h = 8 ft

diameter = 18 ft

so radius = 1/2 of diameter

= 1/2 * 18

= 9 ft

V = 3.14 * 9 * 9 * 8

V =2034.72

---->> V =2034.7 ft^3 (rounded to the tenths place)
