Multiply the diameter of the circle by (pi).
To find the circumference of a circle from its radius, you can use the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius. Simply multiply the radius by 2 and then by π (approximately 3.14). This will give you the total distance around the circle.
all you have to do is find a line with two endpoints on the circle also a diameter is the longest chord on a circle that runs through the middle of the circle.
Find the area of the circle and divide by 4.
Area of a circle = pi*radius2
find the radius of a circle with circumference of 42.1
Equation: circumphrence = diameter * Pi (3.14159)

An engine isn't round, so it would be very difficult to measure the circumference.

Find the area of the circle and divide by 4.
You can find the Antarctic Circle in the Southern Hemisphere.
Area of a circle = pi*radius2
It is twice the radius of a circle
To find the center of a circle in woodworking, draw two diagonal lines from opposite corners of the circle. Where the lines intersect is the center of the circle.
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
find the radius of a circle with circumference of 42.1
