Question

the area of a circle is 24. 64 m square the circumference of circle is

Answer 1

We have area of the circle =24.64 m^2

Let the radius of the circle be rm.

According to question, we get

πr^2 =24.64

→ 22/7 ×r^2 =24.64

→ r^2 =24. 64×7/22

→r^2 = 112×7

→r^2 = 7×7×16

→r=7×4

→r =28.

Thus, radius of the circle=28m

Since , circumference of a circle =2πr units .

→ Circumference of the given circle =2×28×22/7m

=176m
