Question

Circumference of a circle vs perimeter of triangles

Answer 1

heya mate!!

To find the circumference of a circle, take its diameter times pi, which is 3.14. For example, if the diameter of a circle is 10 centimeters, then its circumference is 31.4 centimeters. If you only know the radius, which is half the length of the diameter, you can take the radius times 2 pi, or 6.28.

hope it helps you dear✌️✌️
