Question

An ice cream cone has a diameter of 6 inches and a height of 7 inches. What number can be used to complete the volume statement for the ice cream cone?

Volume = ______?

Answer 1

since we know the diameter of the cone is 6 inches, then its radius must be half that, namely 3 inches.

Answer 2

we are given

diameter=6inches

we know that

diameter=2*radius

so, we get

radius=r=3inch

height=h=7inch

now, we can use cone volume formula

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

we can plug r and h

and we get

`V=(1)/(3) \pi (3)^2(7)`

`Volume= 65.97345 inch^3`..............Answer
