Cell phone has a height of 5 in. and a width of 3 in. What is the screen size diagonal

Answer 1

The screen size diagonal of a cell phone can be calculated using the Pythagorean theorem, which states that the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides.

Applying this theorem, we can calculate the diagonal as follows:

Diagonal^2 = Height^2 + Width^2

Diagonal^2 = (5 in)^2 + (3 in)^2
Diagonal^2 = 25 in^2 + 9 in^2
Diagonal^2 = 34 in^2

Taking the square root of both sides, we find:

Diagonal = √34 in

Therefore, the screen size diagonal of the cell phone is approximately 5.83 inches.
