26.315789, you should use a caculator
Answer:
The third option.
Step-by-step explanation:

Hence the 3rd option.
So to do this one, you have to do the problem backwards!
The equation looks like this with everything plugged in:
272.2 = 2(3.14)r
You are looking for r, so start dividing
272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r
Therefore the radius is about 43.3 in.
I hope I helped!
(m+4)(m+1)
=m^2+5m+4........
The answer is -3
-12c = 43 - 7
-12c = 36
÷ -12 ÷-12
c = -3
