Question

Calculas:
Here's one we haven't worked with before: A circular oil slick of uniform thickness is caused by a spill of 1 cubic meter of oil. The thickness of the oil is decreasing at the rate of 0.1 cm/hr as the slick spreads. (Note: 1 cm = 0.01 m.) At what rate is the radius of the slick increasing when the radius is 8 meters? (You can think of this oil slick as a very flat cylinder; its volume is given by V = pi r2h, where r is the radius and h is the height of this cylinder.)
0.804 centimeters per hour
1.234 meters per hour
0.804
325.201 centimeters
.556 meters ph
