3 Ways to Determine Square Inches - wikiHow

WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have the center at (2,3) and have a radius of 2 since 4 = 2^2. This means if you went a distance of 2 away from that center point you would be on the 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! WebJul 3, 2024 · A = 56.72 square centimeters You can also calculate the area if a circle if you know the radius.
