What is the circumference of a circle with a diameter of 8 meters?
To determine the circumference of any circle, multiply the diameter by pi. Pi is approximately equal to 3.1416
Why do people use Pi?
people use pi to find the circumference of a circle.
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
How do you determine the radius if you know the area and the circumference of a circle?
If circumference(C) is given, then r = C/2(pi) If area(A) is given, then r = (A/pi)1/2
Why do we use pi?
We use it to calculate the circumference of a circle.
What are the two formulae you can use to find the circumference of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter
What is the approximate circumference of the circle. Use 3.14 to approximate pi?
If pi=3.14, then the circumference is ( 3.14 times the diameter).
What do pi have to do with math?
you use pi to calculate the area or circumference of a circle
How do you get circumference for the circle?
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.
What is the circumference of a circle with radius 11.8 in both terms of pi and to the nearest tenth use 3.14 for pi?
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
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
