Circumference of an 8 inch circle

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! WebAs we know, the circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr 2 square units. Now, substitute the values in the perimeter and area of circle formula, we get. The area of circle = πr 2 = 3.14 (5) 2. A = 3.14 (25) A = 78.5 cm 2.
