WebApr 14, 2024 · In the above main () function, we create an instance of the "Circle" class with a radius of 5, and call its methods to calculate the area and circumference. We then modify the radius using the setter method and print the updated area and circumference. Radius of the circle is 5 The area of the circle is 78.53981633974483 The circumference of ... WebSo if we take the principal root of 36, we get r is equal to 6. From there, we can use this to figure out the circumference. So the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we ... WebNov 17, 2009 · Circumference of a circle = pi (sorry but I don't know how to type the symbol) x diameter = 3.14 x diameter (if you round pi) Therefore if diameter=8, circumference = 3.14 x 8 = 25.12 inches. If the 8 inches is the radius, you multiply that by 2 to get the diameter and use the same formula to find the circumference. raymond turk lewisville ar
