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.
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
The formula for the circumference of a circle is pi * diameter or (2 radius.)
Divide by 3.14 then by 2
circumference of a circle = 2*pi*radius or pi*diameter
Divide the circumference by 2*pi because 2*pi*radius = circumference
Circumference = 2 x pi x radius
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
this is called finding the circumference. The formula is 2*pie*radius
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
The formula for the circumference of a circle is pi * diameter or (2 radius.)
pi x 2r
Divide by 3.14 then by 2
circumference of a circle = 2*pi*radius or pi*diameter
1/2 diameter or the circumference/pi/2
the Circumference is pi times 2 times radius If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.
Formula for finding the circumference of a circle: 2 multiplied by pi multiplied by radius
