What is the formula for the area of a circle with a diameter?
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
What is the formula for finding the circumference of a circle with diameter?
PI times the DIAMETER
What is the Circumfrence formula of a circle?
pi times diameter
What is the formula to find the cercumfrence?
2πr (2 times pi times the radius, or pi times the diameter)
How do you find the circumference from the area?
Well, you find the area of a circle by multiplying (pi times radius2) or (pi times radius times radius). The radius is half of the diameter. The formula for the circumference is (pi times diameter). Multiply the radius times 2 to get the diameter. Multiply the diameter times pi.
What is the formula for finding the circumferance of a circle?
Either pi times the diameter or pi times twice the radius (which is the diameter)
If a circle has the diameter of 8 what is the circumfrence?
The formula is circumference= pi times diameter. pi=3.1415926.

What is the formula to find the circumference if the diameter is known?
Times it by pi
What formula do you use to find the radius diameter and circumference of a circle?
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
What is the formula for the circumference of a circle using the diameter measure?
Multiply the diameter times pi.
What is the formula for the area of acircumferenceof a circle is?
area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
