The formula is:
Circumference = (diameter) x (pi)
"Pi" = approximately 3.14159 26535 89792 (rounded)
If you use 3.14, your answer is within about 0.05% of the truth, on the low side.
If you use 22/7, your answer is within about 0.04% of the truth, on the high side.
PI times the DIAMETER
The formula for the circumference of a circle is pi * diameter or (2 radius.)
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
circumference of a circle = 2*pi*radius or pi*diameter
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
PI times the DIAMETER
Circumference of a circle = (pi) x (diameter)
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
The formula for the circumference of a circle is pi * diameter or (2 radius.)
The formula for finding the circumference of a circle is:-circumference of a circle = pi * the diameter of circlewhere The value of pi is approximately 3.14thus the circumference = 3.14*1.5 = 4.71 meters
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
circumference of a circle = 2*pi*radius or pi*diameter
Formula: diameter = pi / circumference
Oh, dude, math time! So, the formula for finding the diameter of a circle from the circumference is dividing the circumference by π (pi). In this case, 49 divided by π is approximately 15.57 centimeters. So, the diameter of the circle is around 15.57 centimeters. Easy peasy, right?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
Circumference or the length (distance around the circle) is pi x D where pi is 3.14159........ and D is the diameter of the circle
