The answer is $3.96. The volume of the cylinder is: V = π * r^2 * h. We know that: r = 1.5 in, h = 7 in, π = 3.14. V = 3.14 * 1.5^2 * 7 = 49.455 in^3. Since the price of the mayonnaise is $0.08 per in^3, then 49.455 in^3 will cost x: $0.08 : 1 in^3 = x : 49.455 in^3. x = 49.455 in^3 * $0.08 : 1 in^3. x = $3.96.

Answer:

Radius of the jar = 1.5 inches

Height of the cylinder = 7 inches

Then

Volume of the cylinder = pie * (Radius)^2 * Height

= 3.14 * (1.5)^2 * 7

= 49.455 cubic inches

Value of 1 inch cube of mayonnaise = 0.08 dollars

Then

Value of 49.455 inch cube of mayonnaise = 0.08 * 49.455

= 3.956 dollars.

= 3.96 dollars.
