# The Mystery of the Circle's Diameter

## Understanding the Circumference

The circumference of a circle is 43.96 kilometers. To find the diameter of the circle, we need to perform some calculations based on the given data.

## Calculating the Diameter

**Step 1:** Divide the circumference (43.96) by 2(pi), which should give you a radius of 6.99.

**Step 2:** Multiply the radius by 2 to get the diameter since the radius is half of the diameter. This gives you a diameter of 13.99.

## Answer

**Answer:** 14 Kilometers

**Explanation:** The circumference is 43.96 kilometers. Replace C by 43.96 in the formula. C=dC≈3.14d. 43.96÷3.14≈d. 14≈d. Therefore, the diameter is about 14 kilometers.

The circumference of a circle is 43.96 kilometers. What is the circle's diameter?

13.99 kilometers is the diameter.
