Answer 2

Given - Radius - x² cm

Height of cylinder - X cm.

Find - Curved Surface Area of cylinder.

Solution - Curved Surface Area of cylinder calculated by the formula = 2πrh. In the formula, r refers to radius and h stands for height.

Thus keeping the values in formula -

2πx²*x

2*(22/7)*x³

44x³/7

Thus, option (2) 44x³/7 is the correct answer.

Curved Surface Area refers to surface area of curved part while Total Surface Area refers to surface area of curved part along with top and bottom.
