Question

What is the volume of this cone?

A)
41.9 ft3

B)
125.6 ft3


C)
240 ft3


D)
501.4 ft3

Answer 1

Option A
`41.9\ ft^(3)`

Explanation:

we know that

The volume of a cone is equal to

`V=(1)/(3)\pi r^(2) h`

In this problem we have

`r=4/2=2\ ft, h=10\ ft`

substitute the values

`V=(1)/(3)\pi (2)^(2)(10)`

`V=41.9\ ft^(3)`
