Question

If a circle has 25 meters of radius, then what is its circumference?

Answer 1

157..............................

Answer 2

So to find the circumference of a circle, the equation is πd.
d=2r.    25 x 2 = 50, so the diameter is 50.
Let us use 3.14 as pi.
3.14 x 50 = 157
The circumference is 157 meters, hope this helps!
