What is the formula to find a radius when given the cicumference?
circumference=pi * diameter radius= 1/2 diameter
How do you find the cicumference of a circle whichout knowing its area radius or diameter?
Given is a circle. Not known is its area A. Not known is its radius r. Not known is its diameter d. You want to calculate its circumference C. Impossible. It cannot be calculated. The only other way is to measure it with a tape measure.
How do you find the radius of a circle if you dont know the circumference?
Well, if you know the diameter you divide that by two to get the radius.
How can you use radius to find the diameter?
you double the radius to find the diameter.
How do you find diameter from radius?
diameter = 2*radius
What is the diameter of a circle if the radius is 27 cm?
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.
How do you find the radius if the diameter is given?
the radius is half the diameter
How do you find the radius of a circle from the diameter?
the radius is half the diameter
How do you find radius when given a diameter?
The radius is half the diameter.
Can you find the diameter by doubling the radius?
Yes, the radius is half of the diameter, therefore the diameter is twice the radius.
What is cicumference in math?
A circumference is the distance around a circle. To find a circle's circumference you need to follow the formula: d*pi The d stands for diameter and pi is 3.14. You need to mulitply the length of the diameter by pi for the circumference. Or, if the diameter isn't given, multiply the radius by 2 and then multiply that by pi.
How do you find the cicumference of a circle?
pi=3.14 it is really long # but we shorten is to 3.14. 3.14 times the diameter
