Circumference of a circle = pi * diameter, or 2(pi) * radius.
The first circle with circumference of 12pi means that the diameter is equal to 12. Since radius is just half of diameter 12/2=6. Same goes for the second circle. Half of 32 is 16. The ratio is then equal to 6:16 or 3:8
=(2t +1)(t -4)
= 2t^2 + 1t -8t - 4
= 2t^2 -7t - 4
