If the circumference of a circle is 5π cm, what is the area of that circle?

To find the area of the circle given its circumference, we can follow a few straightforward steps. The formula for the circumference (C) of a circle is:

C = 2πr

where r is the radius of the circle. In this case, we know that:

5π = 2πr

Next, we can simplify this equation by dividing both sides by π, which gives us:

5 = 2r

Now, solve for r:

r = 5 / 2 = 2.5 cm

Now that we have the radius, we can find the area (A) of the circle using the area formula:

A = πr²

Substituting our value for r:

A = π(2.5)²

Calculating (2.5)² gives us:

(2.5)² = 6.25

So the area is:

A = π × 6.25

This means:

A = 6.25π cm²

Thus, the area of the circle is 6.25π cm².
