Question

What is the lateral surface area of the cylinder shown below?

• A. $220m^2$
• B. $440m^2$
• C. $660m^2$
• D. $880m^2$

Answer 1

The correct option is B $440m^2$

We know that the lateral surface area of a cylinder = $2\pi rh$
Where, $r$ = radius of the cylinder and $h$ is the height of the cylinder.
On substiting the values in the above formula, we get:
Lateral surface area of cylinder = $2\times \frac{22}{7}\times 7\times 10=440m^2$
