Question

A circle has a radius of $14cm$. Calculate its area in ${cm}^2$.

• A. 616

Answer 1

The correct option is A 616
Given:
The radius of the circle, $r=14cm$
Area of a circle, $A=\pi r^2$
$\pi =\frac{22}{7}$
$⟹Area,A=\frac{22}{7}\times 14\times 14$
$⟹A=22\times 2\times 14$
$⟹A=44\times 14=616c{m}^2$.
