Circumference of a three foot circle
Web6. On the circumference of a circle whose radius is 4 feet, we have three points A,B, and C, such that the angle BAC is 41 of one radian. WebTo calculate the length (= the arc length) you need to calculate the whole circumference first and then multiply it by 3/4 to find the length you really want: Whole circumference = 2*Pi*radius = 8*Pi = approx. 25.13dm, The length that you need: (8*Pi) * (3/4 ) = 6*Pi = approx. 18.85dm. Hope that helps!
