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: 2πrh+ 4πr2
Explanation
Curved surface area of cylinder = 2πrhThe curved surface area of hemisphere = 2πr2
Here, we have two hemispheres.
So, total curved surface area = 2πrh + 2(2πr2) = 2πrh + 4πr2
