Question

find the area of the circle whose circumference is 44 cm​

Answer 1

Answer:

circumference is 44 cm

2πr = 44

2 x 22/7 x r = 44

r = 7cm

area of circle = πr²

= 22/7 x 7 x 7

= 154cm²

thus area is 154cm²

Answer 2

$\huge\bold\red{Question}$

Find the area of the circle whose circumference is 44 cm ?

$\huge\bold\green{Solution}$

$\bold{Circumference\:of\:circle}$ = $\bold{44 cm}$

$\bold{Let\: radius\:be}$ $\bold{ = r \:cm}$

$\bold{Formula\:of\:Circumference}$= $\bold{2πr}$

$\bold{2πr = 44\:cm}$

⇒$\bold{2 \times \frac{22}{7} \times r = 44}$

⇒$\bold{r = \frac{44 \times 7}{2 \times 22} = 7 \: c.m}$

$\bold{radius = 7\:c.m}$

$\bold{Area\: of \:circle = πr^2}$

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

=$\bold{(22 \times 7)}$

=$\bold{(154\:cm^2)}$
