If base radius and height of a cylinder are 4 cm and 5 cm, respectively, then find the curved surface area of the cylinder [use π = 3.14].

125.6 cm²

We know that,

The curved surface area of the cylinder = 2πrh

We are given,

The radius of the right circular cylinder = 4 cm

Height of right circular cylinder = 5 cm

So, CSA of cylinder = 2 × 3.14 × 4 × 5

= 40 × 3.14 = 125.6 cm²
