Find the area of a circle given C = 4т.
Give your answer in terms of n.
To find the area of a circle given the circumference C = 4π, we first need to use the formula for circumference, which is C = 2πr, where r is the radius of the circle.
Given C = 4π, we can set up the equation:
4π = 2πr
Dividing both sides by 2π, we get:
r = 2
Now that we have the radius of the circle, we can find the area using the formula for the area of a circle:
A = πr^2
A = π(2)^2
A = 4π
Therefore, the area of the circle is 4π, given C = 4π.
