a stone is thrown into a cylindrical water tank 2 feet in diameter, causing it to rise 1.5 inches. what is the volume of the stone?

Answer 1

Does the tank or the water rise? Your question doesn't make that clear.

Answer 2

the water rises

Answer 3

the change in the volume of the water in the tank equals the volume of the stone

so volume change = Pi(r^2)h, where r is the radius and h is the height
so V = Pi(24^2)(1.5) cu inches
= appr. 2714 cu inches.

Answer 4

24 inches isn't that the diameter
