Web29 sep. 2024 · You may need to use the distributive property to simplify the final answer. For example: Calculate the circumference of a circle with a radius of (x = 1). C = 2πr = 2π (x+1) = 2πx + 2π1 = 2πx +2π = 6.28x + 6.28. If you are given the value of “x” later in the problem, you can plug it in and get a whole number answer. WebThe formula used to calculate circle circumference is: C = 2 · π · r Symbols C = Circle circumference π = Pi = 3.14159… r = Circle radius Radius of Circle Enter the radius of a circle. The radius is the distance between the centre and any point on the outer edge of a circle. Circumference of Circle hotel sakura medan indonesia
