hard math word problem. Help please?
A pool must be drained for maintenance. The pool is shaped cylinder with a diameter of 10m and a depth of 1.5 meters. If water from the pool at a rate of 13m ^ 3 per hour, how many hours pumping it take to drain the pool? Use the value of 3.14 for π and round your answer to the next hour. Please
The formula for the volume of a cylinder is 2Πr ^ 2 + bh A cylinder is 2 Circles and a rectangle, so you add together the two volumes. Diameter is 10, and r is the radius, the half of this type is 5 Connect it to the area bases 2Π cylinder (25) found = 50Π The base of the rectangle on the cylinder diameter of the circle is 10 and the height is 1.5, the height always perpendicular to the ground. The area of the rectangle is bh, 10 * 1.5 = 15 So if you add together the base and lateral surface of the rectangle, of which: 15 50Π Then plug in pi, which is the whole volume of the cylinder. 1570 15 = 1585m ^ 3, since the rate is 13 m ^ 3, you simply divide the cylinder volume, speed, with you so (1585m ^ 3) / (13m ^ 3) = 121.92, the answer would be approximately 121.92 hours.
