Question

1. A cylinder has a diameter of 14ft and height of 10ft what is the volume of the cylinder.
Choices are below.

A.140 ft
B.490 ft
C.350 ft
D.1400 ft

Answer 1

V=πr^2h
V=π49*10
V=490π
V=1538.6
Which would be B

Answer 2

V = πr²h
V = (3.14)(7)²(10)
V = (3.14)(49)(10)
V = (3.14)(490)
V = 1,538.6ft³

It is equal to none of the answers because it is equal to 1,538ft³.
