To determine the circumference of any circle, multiply the diameter by pi. Pi is approximately equal to 3.1416

No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)

people use pi to find the circumference of a circle.

circumference=pi circumference=pi circumference=pi

We use it to calculate the circumference of a circle.

you use pi to calculate the area or circumference of a circle

Circumference of a circle = 2*pi*radius or pi*diameter

If pi=3.14, then the circumference is ( 3.14 times the diameter).

If circumference(C) is given, then r = C/2(pi) If area(A) is given, then r = (A/pi)1/2

Measure the diameter. Multiply the diameter by Pi, this will give the circumference. Pi is approximately 3.1415927 You can use the Pi symbol on a scientific calculator or use 22/7.

They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2

circumference = 2 * pi * radius circumference = 2 * 3.14 * 11.8 circumference = 74.104 Circumference = 2*pi*radius Circumference = 2*3.14*11.8 = 74.104 = 74.1 to the nearest tenth
