What is the diameter of a cirlcle with a circumference of 18.84956?
The diameter is 6 units.
How do you work out the circumference of a cirlcle?
Given the diameter of the circle, multiply it by π (approx 3.14159).
What is the perimeter of 21 mi of a circle?
The perimeter of a cirlcle is its circumference which is: 2*pi*radius or diameter*pi
What is the formula of a circumference?
circumference=r2pi
How do you measure the circumference of a cirlcle?
You need to measure it with something flexible, like a string.If you know for sure it is a circle, it would be easier to measure the diameter, then multiply by pi.
Why the formula of circumference of circle always constant?
Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
How do you determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
Formula for finding the circumference of cone?
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
What are the similarities of Circumference Formula and Area Formula?
They both are a formula
If you have the circumference of a circle what is the diameter?
Formula: diameter = pi / circumference
Formula of circumference?
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
