What is the area of a circle if the circumference is 30cm (express your answer in centimetres)

So before we can find the area, we first have to find the radius. We will do this by using the circumference formula, C = 2πr, to find the radius. Our equation will look like this: 30 = 2πr .

For this, all you need to do is divide both sides by 2π, and your answer will be 4.77 cm = r.

Now that we got the radius, we can solve for the area, which is A = πr^2.

A = π(4.77)^2

A = 22.7529π cm^2 or 71.48 cm^2

the answer is 24
