Question

The circumference of a circle is 44cm. Find its area.

Answer 1

circumference of circle =
$2\pi \: r$
2 pie r = 44cm
so pie×r=44/2
pie×r= 22cm
r=22cm×7/22
r=7cm
area of circle=
$\pi \: {r}^{2}$
22/7×7×7
=154cm^2

Answer 2

the circumference of circle =
$2\pi \: r$
so we make the pie into
$\frac{22}{7}$
and then
$2 \times \frac{22}{7} \times 44$
r = radius then we multiple 44 ÷22 ×7 × 2
$28$
