Question

What is the approximate volume of a cylinder with a diameter of 14 meters and a height of 10 meters? Use 3.14 for pi.

A.
219.8 m3

B.
439.6 m3

C.
1538.6 m3

D.
6154.4 m3

Answer 1

cylinder volume is height times (area of base)
area of base is a circle so
height times pi times radius^2

diameter=2radius
diameter/2=radius
14/2=radius=7

height=10
3.14 is given for pi
10 times 3.14 times 7^2
10 times 3.14 times 49
31.4 times 49
1538.6

the answer is C 1538.6 cubic meters
