Question

The volume of a cone is 300 cubic kilometers. If the radius of the base is 5 kilometers, what is the height of the cone? Use 3.14 for pi Show your work and round to the nearest tenth.

Answer 1

V = 1/3 pi r^2 h
substitute
300 = 1/3 (3.14)(6)^2 h
solve for h
300 = 37.68h
h = 8.0 km

So the hight will be 8.0km

Answer 2

V = 1/3 pi r^2 h
substitute
300 = 1/3 (3.14)(6)^2 h
solve for h
300 = 37.68h
h = 8.0 km

So the hight will be 8.0km

Answer 3

V = 1/3 pi r^2 h
substitute
300 = 1/3 (3.14)(6)^2 h
solve for h
300 = 37.68h
h = 8.0 km

So the hight will be 8.0km
