What is the circumference of a 200m circle?

Question

Its in my homework and i dont know the answer it has a circle with a line through it that says that its 200m and its asking me to find the circumference?

Answer 1

the circumference of a circle is pi multiplied by the diameter of the circle

So C = (pi) x d

, where d = diameter (which is the line through the circle that goes from one side to the other and goes through the centre of the circle)

So in this case, C = pi x 200

C ≈ 3.14 x 200 = 628m

So the circumference is 628m.
