Answer:

1 foot

Step-by-step explanation:

The far above the water is the yellow mark is 1 foot.

Important information:

  • A waterwheel has a radius of 4 feet, and the center of the wheel is 1 foot under the waterline.

Calculation of feet:

[tex]cos \frac{\pi}{3} = \frac{OB}{OA}\\\\ \frac{1}{2} = \frac{OB}{4}\\\\ OB = 2[/tex]

Now

A yellow mark above the water should be

= OB - OD

= 2 - 1

= 1 feet
