Question

The total surface area of a cylinder of base radius r and height h is

Answer 1

Step-by-step explanation:

Total area of the cylinder whose radius is r and height is

h = 2×Pi×rh + 2×Pi×r² = 2×Pi×r(r+h)

Answer 2

Answer:

circumference of the base of the cylinder + curved surface area of the cylinder

2πr^2 + 2πrh

2πr ( r+h)
