Question

The radius of a circle is 7 cm. Find the area and circumference

Answer 1

Questión :-

The radius of a circle is 7cm. Find the area and the circumference.

Solûtion :-

(i) Area of Circle = πr²

• r = 7cm

Substituting values in the formula,

= 22/7 x 7 x 7

= 22 x 7

= 154cm²

_______________________________

(ii) Circumference of a circle = 2πr

• r = 7

Substituting values in the formula,

= 2 x 22/7 x 7

= 2 x 22

= 44cm

The radius of a circle is 7 cm. Find the area and circumference.

We know that :

$\tt{ \purple{ \implies{area \: of \: a \: Circle \: = \pi \: {r}^{2} \: = 154 \: {cm}^{2} }}}$

$\tt{ \purple{ \implies{Circumference\: of \: a \: Circle \: =2 \pi \: r \: = 44 \: cm }}}$
