Question

A cone, a sphere, a hemi sphere and a cylinder stand on equal bases and have the same
height. Then CSA of the cylinder is equal to

Answer 1

Step-by-step explanation:

Answer

Given.

A cone, a hemisphere, and a cylinder stand on equal bases.

Hence radius of base of cone = radius of hemisphere = radius of cylinder=r

And,

They also have same height =h

Hight of cone =h

Hight of cylinder=h

Hight of Hemisphere r=h (r is the radius of sphere)

Now,
