Question

If a cylinder is covered by two hemispheres shaped lid of equal shape, then the total curved surface area of the new object will be

Answer 1

Answer:

2πrh+4πr2

Step-by-step explanation:

Explanation: Curved surface area of cylinder = 2πrh

The curved surface area of hemisphere = 2πr2

Here, we have two hemispheres.

So, total curved surface area = 2πrh+2(2πr2) = 2πrh+4πr2

Answer 2

Answer:

2πrh+4πr squar
