Circumference = 2*pi*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
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
Circumference=2*pi*radius
Circumference = 2*pi*radius
The circumference of a circle with a radius of 6.74 inches is approximately 42.34 inches. The circumference of a circle is found using the circumference formula: Circumference = 2 * π * radius So, all you have to do is plug in the radius into the formula, and approximate π to be 3.14159.
The circumference of a circle with a known radius and can calculated using the following formula: C = 2Π(r)
Circumference = 2*pi*radius So the radius = circumference/2*pi
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
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.

Circumference = (2) x (pi) x (radius)
Circumference=2*pi*radius
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
The circumference of a circle if the radius is 27 inches is: about 169.6 inches. (you can do this type of calculation for other circles using this formula: r x 2 x Pi = circumference).
Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.
