WebThe diameter is equal to two times the radius of a circle. If we draw a straight line from the centre to any point on the circumference of a circle, it is called a radius. We can use the formula ‘2 * Pi * radius’ to calculate the circumference of a circle, where ‘radius’ is the radius for that circle. So, we need only the value of the ... WebThe perimeter of a semicircle formula is defined as the sum of half of the circumference of the circle and the diameter of a circle. It is expressed as, The circumference of a circle is C = πd or C = 2πR. The perimeter of a semicircle formula = (πR + 2R) units, or R(π + 2). where, R = radius of a semicircle; π(pi) is 22/7 or 3.142 ...

WebSep 30, 2010 · Your code silently loses precision in the statements as there is a implicit double to float standard conversion that applies behind your back: circumference = 2 * 3.1416 * radius; (since 3.1416 is of type double, the type of rhs is double). area = 3.1416 * radius * radius; (same here) So, you lose precison.
