Step-by-step explanation:
Ok so as it says, the equation for the circumference (C) is C=2(pi)r.
Pi is about 3.14, so all you have to do is multiply those three values together for the circumference.
C=2•3.14•4
C= 25.12
So the answer would be D, 25.12.

Answer:
Step-by-step explanation:
24m - 12p + 72
factor out a 2
2(12m - 6p + 36) <=== here is one
factor out a 4
4(6m - 3p + 18) <=== and here is another one
