100.34 cubic inches

113.04 cubic inches

226.08 cubic inches

Answer 1

Answer 2

Volume = 113.04 cubic inches

Explanation:

Volume of a cylinder is = πr²h

r = Radius

h = Height

From above

height = 9inches

diameter = radius/2 = 4inches

Radius r = 4/2 = 2inches

Therefore

V = πr²h

V = 3.14 x 2² x 9

V = 113.04 cubic inches
