Question

If the circumference of a circle is $88$ cm, then the area of the circle (in sq.cm) is: $(\text{take}\pi =\frac{22}{7})$

• A. $196\pi$
• B. $92\pi$
• C. $64\pi$
• D. $48\pi$

Answer 1

The correct option is A $196\pi$

$Circumference=2\pi r=88\Rightarrow r=\frac{44\times 7}{22}=14cm$

$\therefore area=\pi r^2=\pi \times 14\times 14$ $c{m}^2=196\pi c{m}^2$
