Question

The circumference of a circle is 13 pi what is the area in square inches

Answer 1

• 42.25π or 132.73 square inches

---------------------

Use the area formula:

• A = πr², where A is the area and r is the radius.

We are given the circumference of the circle, which is C = 2πr.

So, we can set up an equation:

• 2πr = 13π ⇒
• r = 6.5 inches

Now, we can plug this value of r into the area formula:

• A = π(6.5)² = 42.25π
• A = 132.73 square inches (rounded to two decimal places)

Therefore, the area of the circle is 42.25π or 132.73 square inches.
