Question

What is the area of the circle whose circumference is π?

Answer 1

do you know the formula for the circumference of a circle?

Answer 2

C=2πr

Answer 3

good, so you know that:\[2\pi r=\pi\]since you are told that the circumference is equal to \(\pi\). use this to calculate the value for \(r\).

you can then use that to work out the area of the circle.
