Responses:
Double the radius to get the diameter = 14 in
Use the Pythagorean theorem with the height 12 in and the diameter 14 in - 12^2 + 14^2 = d^2
Simplify to get: d^2 = 340
Answer - d is approximately 18.4
Use the Pythagorean theorem with the height 12 in and the radius 7 in - 12^2 + 7^2 = d^2
Simplify to get: d^2 = 193
Answer - d = 96.5
Answer - d = 170
Square the radius to get the diameter = 49 in
Use the Pythagorean theorem with the height 12 in and the diameter 49 in - 12^2 + 49^2 = d^2
Simplify the equation to get: d^2 = 2545
Answer - d is approximately 50.4

To find the approximate diagonal through the cylinder, we can use the Pythagorean theorem.

First, we need to find the diameter of the cylinder, which is double the radius:

1. Double the radius to get the diameter = \(14\) in

Next, we use the Pythagorean theorem with the height of the cylinder and the diameter to find the diagonal:

2. Use the Pythagorean theorem with the height \(12\) in and the diameter \(14\) in:
- \(12^2 + 14^2 = d^2\)

Simplifying:
- \(144 + 196 = d^2\)
- \(d^2 = 340\)

Finally, we calculate \(d\):
- \(d = \sqrt{340} \approx 18.4\)

So, the response for the approximate diagonal through the cylinder is:
- Answer - \(d\) is approximately \(18.4\)
