Question

If a sphere of radius 2r has the same volume as That of a cone with circular base of radius r then find the height of the cone.

Answer 1

volume of sphere = volume of cone

4/3 ×22/7×r×r×r=1/3×22/7×r×r×h
4/3×22/7×2r×2r×2r=1/3×22/7×r×r×h
8r cube/ r square= h
8r= h

Answer 2

Answer:

Step-by-step explanation:

Here it is given that V of both sphere and cones are equal.

So..

We can write it as.

=4/3*22/7*(2r)^3=1/3*22/7*(r)^2*h

=4*2*2*2r=h (after cutting on both sides)

32r=h

Hence , h=32r
