Find the area of a circle whose circumference is 8 pi m

Solution:

Given circumference of a circle is 8π m

We know that the circumference of a circle can be given as 2πr,

where r is the radius of the circle

Now, equate this expression the given value 8π = 2πr

⇒ r = 4 m

We have the area of the circle as πr², we need to substitute r = 4

Area = π(4²)

Area = 16π m²

Therefore, the area of the given circle is 16π m².

Find the area of a circle whose circumference is 8 pi m

Summary:

The area of a circle whose circumference is 8 pi m is 16π m².
