Water is pulled up from a well in a bucket on a rope the winds on a cylindrical drum 15cm in diameter it takes 28turns of the drum to pull the bucket up from the bottom of well how deep is the well? Use the value 22 over for radius

pi = 22/7 I suspect you mean
C = pi D = (22/7) (15 cm)
28 C = 28 (22/7)(15) = 88*15 = 1320 cm = 13.2 meters
