Perimeter of arc length formula
WebSolution: It is given that circumference length = 54 cm. First we will find the radius of the ccircle, i.e. r =. i.e. r =. Also centre angle. Now, we know that arc length of circle using the arc length formula, C =. Now putting values of radius r … WebSep 4, 2024 · It therefore seems reasonable to conclude that the circumference of a circle is about 3.14 times its diameter or 6.28 times its radius. Figure 7.5.3: A regular polygon of 15 sides looks almost like a circle. Theorem 7.5.1. The circumference of a circle is π times its diameter or 2π times its radius, where π is approximately 3.14.
