Round only your final answer to the nearest penny.

Answer 1

$3.96 is the answer.

Explanation:

Answer 2

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.
