Question

The radius and height of a right circular cylinder are $4$ and $14$cm respectively. Find the curved surface area of a cylinder.

Answer 1

The curved surface area of a cylinder is given by the formula, $2\pi \times r\times h$, where $r$ is the radius of the cylinder and $h$ is the height.

Substituting the given values in the formula, we get

Curved Surface Area = $2\times \frac{22}{7}\times 4\times 14$

= $2\times 22\times 4\times 2$

= $352c{m}^2$
