Question

Calculate the area of a circle whose diameter is 14 cm. Take $\pi =\frac{22}{7}$.

• A. 154 $c{m}^2$
• B. 140 $c{m}^2$
• C. 616 $c{m}^2$
• D. 77 $c{m}^2$

Answer 1

The correct option is A 154 $c{m}^2$

Given,
diameter = $14cm$
Radius = $\frac{14}{2}cm=7cm$
Area of the circle = $\pi r^2$
= $\frac{22}{7}\times (7\times 7)$= $154c{m}^2$
