Question

the circumference of a circle is 8
8 cm find its area

Answer 1

Let its radius be r cm , then :
2$\pi$r = 88
$\pi$r = 44
r = $\frac{7}{22}$ * 44
r = 7 * 2
r = 14 cm

Now ,
Area = $\pi$$r^{2}$
        = $\pi$ * 14 * 14
        = $\frac{22}{7}$ * 14 * 14
        = 22 * 2 * 14
        = 616 $cm^{2}$

Answer 2

circumference = 88cm
2 pi r = 88cm
r = 88*7/22*2
r = 14cm

area = 22/7 * r square
        = 22/7 * 14*14
        =616cm sq.
