Question

Find the perimeter and area of the circle of radius 5 cm​

Answer 1

AnsweR :

$\sf \bold{ {78.57}^{2} }$

SolutioN :

$\blue{ \large \boxed{ \sf \pink{\: area \: of \: the \: circle = \pi {r}^{2} }}}$

$\sf \large \: radius = 5cm$

$\sf \rightarrow\pi {r}^{2} \\ \\ \sf \rightarrow \frac{22}{7} \times 5 \times 5 \\ \\ \sf \rightarrow \frac{22}{7} \times 25 \\ \\ \sf \rightarrow \frac{ \cancel{550}}{ \cancel7} = 78.57 {cm}^{2}$

Answer 2

so this is the required answer
