WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4. WebMar 12, 2024 · Using Standard Method. The formula for the circumference of a circle is c= (2*22*r)/7. The radius value will store into the variable “r”. By substituting the “r ” value into the formula we will get circumference value, that value will store into the variable “c”. 1. WebThis program is divided in two functions: addition and main.Remember that no matter the order in which they are defined, a C++ program always starts by calling main.In fact, main is the only function called automatically, and the code in any other function is only executed if its function is called from main (directly or indirectly).
