Question

find the area of circle whose circumfrence is 22​

Answer 1

Answer:

circumference=22cm

r=3.5cm

Area=πr²

22/7×3.5×3.5=38.5cm²

Hope it helps you

Answer 2

The area of the circle is 38.465 m^2

The area of a circle is determined by the total area covered by the circle.

It can be determined by the formula,

Pi*r^2

Where pi is a Greek word whose value is 22/7.

R is the radius of the circle I.e, the straight distance between the centre and the circumference.

Given, circumference of the circle is 22.

I.e, 2*pi*r=22

Or, r=7/2.

Hence, area can be obtained by pi*r^2=3.14*(7/2)^2=38.465 m^2
