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.
