Answer:
88.6
Step-by-step explanation:
A=4(pi)r^2/3
D=9.2 : r=4.6
A=4(3.14)(4.6^2)/3=88.5898667
A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.
B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.
how many months for the cost to be the same?

well, since the cost for both is the same, we can just get A's, knowing that B is the same
