Answer:
C= 157
Explanation:
The formula for the circumference of a circle is 2 · pi · r (radius)
So your problem would look something like this:
C= 2 · pi · r
C= 2 · 3.14 · 25
C= 157 in.
the formula for the circumference of a cirlce is πd. the diameter is 2r which in this case is 0.5. therefore the circumference is 0.5π, or 1.5708 (rounded)
