The curved surface area of the cylinder, given the circumference and the height, is 24.1 cm²

How to calculate the curved surface area of the cyclinder?

We shall begin by calculating the radius. Details below:

  • Circumference (C) = 4 cm
  • Radius (r) = ?

C = 2πr

4 = 2 × 3.14 × r

4 = 6.28 × r

Divide both sides by 6.28

r = 4 / 6.28

r = 0.64 cm

Finally, we shall calculate the curved surface area of the cylinder. Details below:

  • Radius (r) = 0.64 cm
  • Height (h) = 6 cm
  • Curved surface area of cylinder =?

Curved surface area of cylinder = 2πrh

= 2 × 3.14 × 0.64 × 6

= 24.1 cm²

Thus, the curved surface area of the cylinder is 24.1 cm²
