Question

Please help?
The volume of a cone is 300 cubic kilometers. If the radius of the base is 7 kilometers, what is the height of the cone? Use 3.14 for pi. Show your work and round to the nearest tenth.

Answer 1

simply plug the information you were given into the volume formula for a cone:

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

Answer 2

I dont get it though :(

Answer 3

300=(1/3)(3.14)(7^2)(h)

Answer 4

solve for h

Answer 5

Plug the values that you're given in the problem into the formula for Volume of a Cone:
\[300={1\over3}(3.14)(7)^{2}h\]
Solve for h.

Answer 6
