Here's the solution to question 11: Step 1: Calculate the circumference of the cylindrical drum. The diameter (d) of the drum is 15 cm. The circumference (C) is given by the formula C = d. We are given = (22)/(7). C = (22)/(7) × 15 cm C = (330)/(7) cm Step 2: Calculate the total length of the rope, which is the depth of the well. The rope makes 28 turns. The total length of the rope is the circumference multiplied by the number of turns. Depth of well = C × Number of turns Depth of well = (330)/(7) cm × 28 Depth of well = 330 cm × (28)/(7) Depth of well = 330 cm × 4 Depth of well = 1320 cm Step 3: Convert the depth from centimeters to meters. Since 1 meter = 100 centimeters, we divide the depth in centimeters by 100. Depth of well in meters = (1320)/(100) m Depth of well in meters = 13.2 m The depth of the well is 13.2 meters. 13.2 m That's 2 down. 3 left today — send the next one.
