Question

The area of a circle is 24.64 m square the circumference of the circle is

Answer 1

In general , Area of a circle whose radius is r is,
πr²,

And circumference of a circle whose radius is r is 2πr,

Now equal the first formula to the question to get radius and to calculate circumference,

Let π = 22/7, for accurate answer,

Now 22/7 * r² = 24.64 m²,
=> r² = 7.84 m²,
=> r = 2.8 m,

Now keeping this value of r in 2md formula to find circumference of the circle,

=> Circumference = 2*π*r , Again assume π = 22/7,

=> Circumference = 2*22/7* 2.8 m
=> 17.6 m,

Therefore the circumference of the circle is 17.6 m,

Hope you understand, Have a great day !

Thanking you, Bunti 360 !

Answer 2

πr^2=24.64
πr=√24.64=4.96
r=4.96/π=4.96*7/22=1.57
2πr=2*22/7*1.57=9.86
