## stillfly122 Group Title If a sphere has a radius 15 m, what is the volume of the hemisphere? one year ago one year ago

Use the formula for the volume of a sphere: $V=\frac{ 4 }{ 3 }\pi r^3$Because it's a hemisphere, you know what to do next...

Actually, I don't know what to do next D:

Well, r = 15. Put it in the formula...

This will give you the volume of a sphere with a radius of 15. (use calculator). Now think what you have to do to calculate the volume of a hemisphere with the same radius ;)
