Question

Taking pi is equal to 22 by 7 find the radius of the circle whose are used area are 22 by 7 cm sq

Answer 1

Answer:

Area of the circle = πr²

22÷7 = 22÷7 × r²

r = 1

Answer 2

Answer:

Radius = 22/7

THE FORMULA :

$\pi \: r \: ^{2}$

$\frac{22}{7} \times \frac{22}{7} = 1cm ^{2}$

$so \: the \: answer \: is \: 1 |r| radius$
