The circumference of a circle is 20π. What is the area of the circle?
Shkiper50 [21]

Answer:

The area of the circle is 100 square units.

Step-by-step explanation:

We are given that the circumference of a circle is 20π, and we want to determine its area.

Recall that the circumference of a circle is given by the formula:

\displaystyle C = 2\pi r

Substitute:

20 \pi = 2 \pi r

Solve for the radius:

\displaystyle r = \frac{20\pi}{2\pi} = 10

The area of a circle is given by:

\displaystyle A = \pi r^2

Since the radius is 10 units:

\displaystyle A = \pi (10)^2

Evaluate:

\displaystyle A = 100\pi\text{ units}^2

In conclusion, the area of the circle is 100 square units.
