Answer:

 =1004.8 in^2

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We have the diameter of 8

r = d/2 = 8/2 =4

   = 3.14 * 4^2 *20

    =1004.8 in^2

Answer:

1005.30

Step-by-step explanation:

h=20d=8

identify variables

r=

r=

\,\,4

4

radius is half of the diameter

V=

V=

\,\,\pi r^2h

πr  

2

h

use volume of a cylinder formula

V=

V=

\,\,\pi(4)^2(20)

π(4)  

2

(20)

substitute variables into formula

V=

V=

\,\,1005.30964915

1005.30964915

multiply

V=

V=

\,\,1005.3\text{ in}^3
