Question

A cone shaped cup has a radius of 5 inches and a height of 12 inches. What is the exact value of the volume of the cup?

27π in3
9π in3
100π in3
300π in3

Answer 1

Volume = 1/3*πr^2*h
= 1/3*π*5^2*12
= 100π in^3

Answer 2

`\text{Volume of a cone = } (1)/(3) \pi r^2h`


`\text{Volume of a cone = } (1)/(3) \pi (5)^2(12) = 100 \pi \text{ in}^3`

Answer: 100π in³ (Option C)
