Answer:

2827 cm

Explanation:

The formula for the circumference of a circle is 2*pi*radius, meaning that to find the radius you would need to divide the circumference by 2*pi. By doing this, you get that the radius is 30cm. Now, the formula for area of a circle is pi * radius^2. Plugging the radius in, you get 30^2 * pi, which is equal to 900pi cm. This is about 2827 cm when you use a calculator.
