Question

The circumference of a circular table is 88 m. Find its area.

Answer 1

Circumference of circle = 88 m
2πr = 88 m

${\displaystyle 2\times \frac{22}{7}\times r=88}$

${\displaystyle r=\frac{88\times 7}{2\times 22}}$

r = 14 m

Area of circle = ${\displaystyle \pi r^2}$

= ${\displaystyle \frac{22}{7}\times 14\times 14}$

= 616 m²
