Question

A disk is in the form of square and measures 5.25inches on each side. Find the diagonal length of thedisk. I am taking geometry In the 8th grade and I am lost

Answer 1

The diagonal length is 7.42 inches.

Step-by-step explanation:

The disk with its diagonal is:

Then, we can look at the diagonal as the hypotenuse of a right triangle. Then, if we call D to the diagonal:

`\begin{gathered} D^2=(5.25in)^2+(5.25)^2 \\ D=√(2(5.25in)^2)\approx7.42in \end{gathered}`
