Radius of baseofa right circular cone and a sphere is each equal to r. If the sphere and the cone have the same volume. then what is the height of the cone?
Volume of cone and sphere are equal.
$$ \frac{1}{3} \pi r^2 h = \frac{4}{3} \pi r^3$$
Since radius for both of them is equal ,
h =4r
So, the answer would be option b)4r.
