Step-by-step explanation:
The formula for calculate the volume of a cylinder is:

r is the radius of the cylinder and h is the height of the cylinder.
Given the diameter of 3 inches, calculate the radius of the cylinder with:
(Where d is the diameter)

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

Digit 1:1,3,5,7, or 9.
Digit 2: 0,1,2,3,4,5,6,7,8 or 9.
4*10= 40 possible codes.
This will be false because that’s not the average winter temperatures in 45 states
