Best ResponseYou've already chosen the best response.1So the sphere must have had the same volume. But the volume of a sphere is: \[V=\frac{4}{3}\pi r^3=80\pi\]

Best ResponseYou've already chosen the best response.1\[A=\frac{1}{2}(4)(2\sqrt{3})=4\sqrt{3}=6.93\]

anonymous

Best ResponseYou've already chosen the best response.0oh so the answer is 6.93?

Mertsj

Best ResponseYou've already chosen the best response.1That is the area of the base. To get the volume, you have to multiply that by the height.

anonymous

Best ResponseYou've already chosen the best response.1See that picture? You have to take the area of the triangle and multiply it by the height of the prism which is 10

anonymous
