Using π = 22/7, find the curved surface area of a cylinder with radius 14 cm and height 58 cm.
Note
Curved surface area of a cylinder = 2πrh. So CSA = 2 × 22/7 × 14 × 58 = 5104 square cm. This excludes the two circular ends. Think of a cylinder as many equal circular layers stacked up. So we find the circular base area πr² and multiply by the height. The answer is in cubic units, so the correct choice is 5104 cm².
