Question

The curved surface area of a cylinder with radius 20cm and height 5cm is _____ cm|2

Answer 1

= 628.57 cm² is the answer

Answer 2

Formula for curved surface area = 2πrh

So we apply the formula to looked for the curved surface area of the cylinder:

Curved surface area = 2π(20)(5) = 629 cm²

Answer: The curved surface area is 629 cm²
