Question

the circumference of a circle is 11 cm find its area​

Answer 1

this is the answer.....
I.e 77/8=9.625cm^2

Answer 2

$Circumference \: of \: the \: circle = 11 cm$

$= > 2\pi r= 11 cm$

$= > 2 \times \frac{22}{7} \times r= 11 cm$

$= > r= 11 cm \times \frac{7}{22} \times \frac{1}{2}$

$= > r= \frac{7}{4} cm$

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

$= \frac{22}{7} \times \frac{7}{4} \times \frac{7}{4}$

$= \frac{77}{8} {cm}^{2}$
