In a circle the length of an arc is given by

WebWe will use the formula for arc length of a circle given an angle in radians: S = Rθ. We already know that R = 9 feet and θ = π/3, so we get: S = 9 (π/3) S = 3π. The arc length is 3π feet, or approximately 9.42 feet. Note that this arc length is 1/6 of the circumference, since C = 2πR = 2π (9) = 18π. WebDiameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle. It is equal to twice …
