Answer 1

RIGHT CIRCULAR CYLINDER:
Right Circular Cylinder is a solid figure obtained by revolving the rectangle about its one side.

SPHERE:
A sphere is a solid generated by the revolution of a semicircle about its diameter.

SOLUTION:
Given:
Radius of the right circular cylinder = Radius of the sphere = r cm

DIAMETER OF THE SPHERE = r +r = 2r.
