Question

find the area of the circle whose circumferenceis88cm? 22/7 answer please​

Answer 1

Given circumference = 88 cm

=> 2*pi*r=88

=>r= 88*7/22*1/2

=> r= 14cm

Area of circle= pi* r^2

= 22/7*(7)^2= 154 cm2

Answer 2

Step-by-step explanation:

$Circumference of a circle = 2\pi \:r \\ 88 = 2 \times \frac{22}{7 } \times r \\ 88 = \frac{44r}{7} \\ 44r = 88 \times 7 \\ r = \frac{88 \times 7}{44} \\ r = 14cm \\ area \: of \: circle \: = \pi \: {r}^{2} \\ = \frac{22}{7} \times 14 \times 14 \\ = 22 \times 2 \times 14 \\ = 616 {cm}^{2}$
