Find the circumference for 15 inches
The circumference of a circle is calculated using the formula:
Circumference = 2 * π * r
Where π (pi) is a constant approximately equal to 3.14159 and r is the radius of the circle.
If given the diameter of the circle instead, you can calculate the radius by dividing the diameter by 2.
In this case, if the diameter is 15 inches, the radius would be:
Radius = 15 / 2 = 7.5 inches
Now, substitute this radius into the formula:
Circumference = 2 * 3.14159 * 7.5
Circumference = 47.12395 inches
Therefore, the circumference of a circle with a diameter of 15 inches is approximately 47.12 inches.
