The circumference of a circle is given by the formula 2πr, where r is the radius of the circle. Substitute the given circumference into this formula and solve for r.
30π= 2πr.
Therefore, the radius of the circle is 15. Use this to find the area of the circle. The area of a circle is given by the formula A=πr
