Circumference of a circle c 2πr solve for r
WebYou have to find circumference of a circle. Pi comes here because of its ratio. 2 and r comes because it equals the diameter. So pi times 2 times r is basically circumference over diameter times diameter which gives circumference. So that is where 2*pi*r comes from.

WebTo find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28 = 176 cm. Therefore, the circumference of the circle is 176 cms. Example 2: The circumference of a wheel is 440 cm. Find its radius and diameter. Solution: Given, the Circumference of the wheel = 440 cm Circumference of a circle formula = 2πr Weba) The circumference C of a circle is given by C(r)=2πr, a function of its radius. Solve the equation C = 2πr for r: C = 2 π r. Divide both sides by 2π: r = C 2 π. Therefore, the function r(C) is: r (C) = C 2 π. The above function gives us the radius of a circle in terms of its circumference. b) To find r(26π), Substitute 26π for C in ...
