Do you multiply to get perimeter?
No, you add up all the sides. Yes, in terms of a circle. To determine the perimeter or circumference of a circle, you must multiply: 2πr or two times Pi times the radius of the circle.
If the radius equals 2cm what is the circumference?
C = 2 * (pi) * (radius) So plug in 2 for radius C = 2 * (pi) * (2) C= 4(pi) If you need to approximate multiply 4 times 3.14. If you do not need to approximate then your answer is 4(pi)
