**Ms. Sue**, Sunday, April 7, 2013 at 5:54pmLet's change the inches to feet.

SA = 4 * 3.14 * 0.5^2

SA = 6.28 sq. feet

(500 * 6.28)/175 = 17.94 = 18 quarts

**Steve**, Sunday, April 7, 2013 at 5:54pmarea of 1 buoy: pi d^2 = 144pi

so, quarts of paint:

q = 144pi * 500 / 175

**Steve**, Sunday, April 7, 2013 at 5:55pmoops - Go with Ms Sue - I forgot to change inches to feet.

- Geometry -- Mine is wrong -
**Ms. Sue**, Sunday, April 7, 2013 at 6:00pmAnd I forgot to square the radius.

SA = 4 * 3.14 * 0.5^2

SA = 3.14 square feet

(500 * 3.14)/175 = 8.97 = 9 quarts
