If a pool table measures 4 ft by 8 ft, what is the diagonal length from the bottom right pocket to the nearest tenth?

8.9 ft

Step-by-step explanation:

Use Pythagorean theorem,

a² + b² = c²

√ (a² + b²) = c

The diagonal is the hypotenuse of the rectangular pool table.

So,

√ (4² + 8²) = c

√ (16 + 64) = c

√ (80) = c

8.944 ... = c

Nearest tenth:

8.9

The answer is 8.9ft maybe
