Question

A cylinder has a base with a radius of 5 cm and a height of 15 cm. What is the volume of the cylinder? (Use π = 3.14.) A. 471 cm3 B. 1177.5 cm3 C. 4710 cm3 D. 235.5 cm3

Answer 1

calculated using (pi)x r^2 x h
so 3.14 x 25 x 15
answer there for is B. 1177.5

Answer 2

The formula for volume is

`V=\pi r^(2)h`
We plug in:

`V=\pi (5)^(2)(15)`

`=\pi (25)(15)`

`=375\pi`

`=375*3.14=1177.5`
