What is the curved surface area (in cm2) of a right circular cylinder whose height and diameter are 10 cm and 8 cm respectively?

20π 80 π 160 π 40 π

80 π

We know that, The curved surface area of a right circular cylinder = 2πrh We have, Diameter = 8 cm Radius = \(\frac{ 8 }{2}\) = 4 cm  The curved surface area of a right circular cylinder = = 2π × 4 × 10 = 80 π cm2
