WebUse this circle calculator to find the area, circumference, radius or diameter of a circle. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. Units: Note that units of length are … WebSep 30, 2010 · 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. Don't do it unless it is intentional. Compile with the strictest warning level though that is not guaranteed to bring out all lurking issues.
WebBut, if Radius < 1cm, Then the value of r*r is also a decimal. If, Diameter is 0.5cm The r=2.5cm Therefore, the Area is (pi)r^2 A = (pi)0.25*0.25 = 0.0625(pi) There is no rule that if Radius or Diameter is a decimal, then the Area and the Circumference is also decimal but it ALMOST always shows up that way. Even if it is a decimal no difference.
