Current Attempt in Progress Gasoline is pouring into a vertical cylindrical tank of radius 3 feet. When the depth of the gasoline is 7 feet, the depth is increasing at 0.4 ft/sec. How fast is the volume of gasoline changing at that instant? Round your answer to three decimal places. The volume is changing at a rate of i feet per second.Current Attempt in Progress Water is being pumped into a vertical cylinder of radius 6 meters and height 18 meters at a rate of 4 meters /min. How fast is the water level rising when the cylinder is half full? Round your answer to three decimal places. The water level is rising at a rate of HI meters per minute.A spherical snowball is melting. Its radius is decreasing at 0.3 cm per hour when the radius is 20 cm. How fast is its volume decreasing at that time? NOTE: Enter the exact value or round to three decimal places. The volume is decreasing by cm per hour.Current Attempt in Progress A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decreases. If the length of the cylinder is increasing at 0.1 cm per second, find the rate at which the radius is changing when the radius is 1 cm and the length is 5 cm. Enter the exact answer. dr dt HI cm/sec
