4) 62.8 cm^2
5) It is quadrupled
5 by the 3 is 5X5X5 = 125
125-4 = 121
answer = 121
Answer:
I think it's B I hope this is the right answer.
The way to solve this question is to essentially reverse the equation I used in the other answer.
I would solve this with some theoretical values. If you start with 3, how long would it take for it to triple, or reach 9.
the equation would look like 9 = 3(2)^t/6, note how the instead of 1/2 it is now 2 in the parenthesis, as it doubles every 6 hours rather than halves every amount of hours.
When placed into an algebra calculator, the answer should be about 9.5 hours
