Question : 96 of 200

Marks: +1, -0

The radius of the base of a right circular cylinder is r and the radius of a sphere is

r/2

If the volumes of that cylinder and the sphere are equal, then the height of the circular cylinder in proper units is

Solution:

Volume of cylinder = Volume of sphere

πr^{2}h={4}/{3}π({r}/{2})^{3}⇒h=({4}/{3×8})r

∴h={r}/{6}
