Question

find the radius of a circle if its area is 4 22÷7 cm2​

Answer 1

*Answer*:

Radius of the circle= 2 cm

*Step-by-step explanation*:

Given,

Area of circle=4 22/7 cm²

We know that

The formula for finding the area of circle is πr²

So we can say that

→πr²=4 22/7

→π=22/7

So →22/7 r²=4 22/7

By cancelling 22/7 on both sides, we get

→r²=4

→r²=2²

Taking square roots on both sides

→r=2 cm
