Question
The circumference of a circular table is $88 m$. Find its area.
✓
Answer
Circumference of circle $=88 m$
$ 2 \pi r =88 m$
$ 2 \times \frac{22}{7} \times r=88$
$ r=\frac{88 \times 7}{2 \times 22}$
$ r =14 m$
Area of circle $=\pi r^2$
$ =\frac{22}{7} \times 14 \times 14$
$ =616 m ^2$
$ 2 \pi r =88 m$
$ 2 \times \frac{22}{7} \times r=88$
$ r=\frac{88 \times 7}{2 \times 22}$
$ r =14 m$
Area of circle $=\pi r^2$
$ =\frac{22}{7} \times 14 \times 14$
$ =616 m ^2$
