Does anyone know this need help! Thanks!

Answer 1

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.

Answer 2

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)
