What is the curved surface area (in cm2) of a right circular cylinder whose height and diameter are 10 cm and 8 cm respectively?
Answer & explanation
Correct answer: option 2
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
