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].
Answer & explanation
Correct answer: option 1
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
