Question

Find the volume of a hemisphere with a radius of 8. Round to the nearest tenth.

Answer 1

the answer is V(hemisphere) = 1072.3in^3

Explanation:

Answer 2

V(hemisphere) = 1072.3in^3

Explanation:

To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.

The volume of a sphere is:

`V(sphere) = (4)/(3) \pi r^3`

Let's plug in the radium of 8 into the equation and solve:

`V(sphere) = (4)/(3) \pi (8)^3\\V(sphere) = (4)/(3)\pi 512 \\V(sphere) = 2144.660585`

Now, divide it by 2

V(sphere) = (2144.660585)/2

V(hemisphere) = 1072.3in^3

I hope this helps!!
