Well first, we need to know the formula for the circumference of a circle to find the diameter.
The formula is 2PiR, 2 • 3.14 • R, or 3.14 • D.
We have our circumference, 88.
Let's divide out our current numbers to find the diameter.
"3.14 • D = 88" is our equation.
To solve for D, we need to divide by 3.14 on both sides.
3.14(D) / 3.14 = D
88 / 3.14 = 28.0254
You're left with:
D = 28.0254.
Your answer is:
The diameter of the circle is 28.0254 ft.
I hope this helps!
