Question

The area of a circle is 132.7 square cm. Find the diameter.

Answer 1

Answer:

13

Step-by-step explanation:

To find the diameter, use the diameter formula.

d = 2r (r = radius)

In this case, we don't have a radius so to find the radius, use the radius formula.

r = $\sqrt{A/\pi }$ (A = area)

So, r = square root of 132.7/pi

r is approximately 6.5

Now we have the radius so we can find the diameter:

d = 2(6.5)

d = 13

Diameter is 13

Answer 2

Answer:

The diameter of the circle is 13.
