Question

find the area of a circle whose circumference is 88cm.

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

Given, 2πr = 88 cm

$\bf\huge r=\frac{88\times7}{2\times22} = 14 cm$

Area = πr^2

Area = $\bf\huge\frac{22}{7} \times14\times14$

Area = 616 cm^2
