7-8 Factoring By Grouping The volume of a cylinder can be determined using the formula V=πr2h, where r and h represent the radius and height of the cylinder, respectively. A volume of paint expressed as (8x3 + 31x2 + 32x)π and a volume of paint expressed as (10x3 + 17x2)π are poured into a paint can in the shape of a cylinder. Determine possible expressions for the radius of the can and the depth of the paint in the can.

A. The radius can be expressed as 2x and the depth can be expressed as 3x + 4.
B. The radius can be expressed as 3x + 4 and the depth can be expressed as 2πx.
C. The radius can be expressed as 2πx and the depth can be expressed as 3x + 4.
D. The radius can be expressed as 3x + 4 and the depth can be expressed as 2x.
