Question

Find the volume of a cylinder with a 9-inch height and a 3-inch radius
(i = 3.14).
A. 35.36 cubic inches
B. 89.78 cubic inches
C. 169.56 cubic inches
D. 254.34 cubic inches
​

Answer 1

Answer:

D. 254.34 cubic inches

​Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

Where r = 3 in and h = 9 in

V = (3.14) * (3)^2 *9

V = 254.34 in ^3

Answer 2

Answer:

volume of a cylinder= \pi*r^2*h

81*pi

=254.34 in^3
