## The area of a circle is 615.44 sq. inches. What is the diameter of the circle? use 3.14 for π.

**The diameter of the circle is 28 inches.**

To find the diameter of the circle, we can use the formula for the area of a circle:

A = π × r^2

Where:

- A is the area of the circle
- π is approximately 3.14
- r is the radius of the circle

We know the area of the circle is 615.44 sq. inches. So, we can rearrange the formula to solve for the radius (r):

r^2 = A / π

r^2 = 615.44 / 3.14

r^2 = 196

Taking the square root of both sides, we get:

r = √196

r = 14

Now, we have the radius of the circle, and to find the diameter (d), we simply double the radius:

d = 2 × r

d = 2 × 14

d = 28

So, the diameter of the circle is 28 inches.

## How to Find the Area and Circumference of the Circle?

Here are the formulas and steps for finding the area and circumference of a circle in plain text:

Area of a Circle (A): A = π * r^2

Circumference of a Circle (C): C = 2 * π * r

Steps to Find the Area:

- Measure the radius of the circle.
- Square the radius (multiply the radius by itself).
- Multiply the squared radius by π to find the area.

Steps to Find the Circumference:

- Measure the radius of the circle.
- Multiply the radius by 2, then multiply by π to find the circumference.
