hope it helps!!!!!!!!!!

Answer 2

C

Explanation:

The center of the large circle is Center D. It has can area of 900 pi square units. This means that according to the formula of the area of circle,

`\pi {r}^(2)`

• The radius of the large circle is 30.
• The diameter of the large circle is 60.

Since Point D is the center of the large circle, by definition of a circle, diameter, and radius.

• AD=30, DB=30, and AB=60.

The area of the 3 small circles are equal so this means that the radius,any physical characteristics of the 3 circles are equal.

This means that each diameter of the 3 circles equally divide the diameter of the large circle into 3 equal parts.

This means Circle C diameter is 20.

Circumference is

`\pi d`

The diameter is 20 so the circumference of Circle C is

`20\pi`
