For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
diameter*pi = circumference
Diameter = circumference/pi
To get the circumference of a circle first you have to find the diameter of the circle and multiply the diameter by Pi (3.14 in short). so it is the diameter * Pi.
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
The ratio of a circle's circumference to its diameter is Pi, which is 3.14159. Hence, multiply the diameter by Pi to find a circle's circumference, or divide a circumference by Pi to find its diameter. 8 times pi = 25.13274123.
The distance across a circle through the center is called the diameter. The distance around a circle is called the circumference. Pi is the ratio of the circumference of a circle to the diameter. So,2 radius x Pi = circumferencePi is approximately 3.14159265358979323846...
Diameter of a circle = circumference/pi
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
Divide the known circumference by pi to find the diameter of the circle.
circumference/pi = diameter
diameter*pi = circumference
Diameter = circumference/pi
Divide the circumference by Pi to find the diameter.
To get the circumference of a circle first you have to find the diameter of the circle and multiply the diameter by Pi (3.14 in short). so it is the diameter * Pi.
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
