How to solve the circumference of a circle
WebSep 29, 2024 · There are two formulas that can be used to calculate the circumference of a circle: C = 2πr or C = πd, where π is the mathematical constant approximately equal to 3.14, [4] r is equal to the radius, and d is equal to the diameter. [5] Because the radius of a circle is equal to twice its diameter, these equations are essentially the same. WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps! ( 9 votes) Flag
