What is the exact volume of the cylinder?

32π

in³

64π

in³

128π

in³

512π

in³

Step-by-step explanation:

The question is incomplete. Here is the complete question;

'What is the exact volume of the cylinder? 32π in³ 64π in³ 128π in³ 512π in³ Cylinder with radius labeled 4 inches and height labeled 8 inches'

Volume of a cylinder = πr²h

r is the radius of the cylinder

h is the height

Given r = 4in

h = 8in

Volume =  π(4)²*8

volume of the cylinder = 16π*8

volume of the cylinder = 128πin³

so, converting firstly the mixed fractions to improper fractions and then "adding".
