You're in the right place! Question 2: Find the radius of the circle having C = 50 cm. To calculate what is the circumference of a 2 inch diameter circle, use the formla of C = 2πr, where r is the radius. It was originally defined as the ratio of a circle's circumference to its diameter (see second formula below on why) and appears in many formulas in … The circumference of a circle is the length of the outside boundaries of the circle. Below, you can learn all about what you define as a circumference, how to find it, and how to convert it to the diameter. The area of a circle is: π times the Radius squared: A = π r 2. or, when you know the Diameter: A = (π /4) × D 2. or, when you know the Circumference: A = C 2 / 4 π. Solution: Since the diameter is known to us, we can calculate the radius of the circle, Therefore, Circumference of the Circle = 2 x 3.14 x 2 = 12.56 cm. You can work out the circumference to the area, the radius, and the diameter as well. Dimensions of a Circle Such a calculator works in all directions, which is convenient.
