The circumference of a circle is 30t. what is its area?

given the circumference is 30t.

Step-by-step explanation:

The circumference of a circle is and the area of a circle is assuming the radius is for the circle in question.

We are given the circumference of our circle is .

If we solve this for r we get: .  To get this I just divided both sides by since this was the thing being multiplied to .

So now the area is .

Simplifying this:

.

30/2=15 so:

.

Squaring the numerator and the denominator:

Using law of exponents or seeing that a factor of cancels:
