Question

What number can be used to complete the volume statement for the cone? A cone with height 4 meters and diameter 3 meters.

Answer 1

The person above me is wrong, the answer is 3

Explanation:

I got it right on the test

Answer 2

Explanation:

The formula of a volume of a cone:

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

r - radius

H - height

We have

`H=4m;\ 2r=3m\to r=1.5m`

We have everything we need to calculate the volume of the cone.

`V=(1)/(3)\pi(1.5)^2(4)`

If we want to get the approximate volume, we must use the approximation of the number π.

`\pi\approx3.14;\ \pi\approx(22)/(7)`

`V=(1)/(3)\pi(2.25)(4)=(9\pi)/(3)=3\pi\approx(3)(3.14)=9.42\ (m^3)`
