Question

the area of a circle is equal to the area of rectangle with side 112 m and 88 m respectively .find the circumference of the circle

Answer 1

Length of rectangle = 112m
Breadth = 88m

Area of rectangle = length × breadth

= 112m × 88m

= 9856m²

Circumference of circle = πr²

$9856 = \frac{22}{7} \times {r}^{2}$

$\frac{9856 \times 7}{22} = {r}^{2}$

$r {}^{2} = 3136$

$r = \sqrt{3136}$

$r = 56m$


Circumference = 2πr

$= 2 \times \frac{22}{7} \times 56$

= 392 m
