Let be the radius and height of cylinder A, and be the radius and height of cylinder B.
We know that . Since the diameter of cylinder B is 12, its radius is 6.
Since the diameter of cylinder B is 4 inches greater than that of cylinder A, the diameter of cylinder A is 8, which implies that its radius is 4.
The formula for the volume of a cylinder is
And we have
Which means that the volume of cylinder B is 108/48=2.25 times greater than the volume of cylinder A
Answer: 1 feet = 12 inches
1 cubic feet = 12^3 = 1728 cubic inches
15 cubic feet = (15)(1728) = 25,920 cubic inches

Eliza started out with $324.18 on Jan. 18th and had outstanding cheques of $15.00+77.49+$124.28=$216.77. So her actual balance was $324.18-$216.77=$107.41. Now she has $487.38 so $487.38-$107.41=$379.97 balance for the deposited amount.
