Please explain clear and easy way such as step by step . It's will be easy for me to understand.

The radius of a cone is increasing at a constant rate of 4 meters per second, and the volume is increasing at a rate of 904 cubic meters per second. At the instant when the radius of the cone is 10 meters and the volume is 489 cubic meters, what is the rate of change of the height? The volume of a cone can be found with the equation V = Trzh. Round your answer to three decimal places. A rectangle has a length of 7 inches and a width of 1 inches whose sides are changing. 2 ) The length is increasing by 3 in/sec and the width is shrinking at 5 in/sec. What is the : rate of change of the area? 3 ) A right triangle has legs of 15 inches and 20 inches whose sides are changing. The short leg is decreasing by 5 in/sec and the long leg is growing at 9 in/sec. What is the rate of change of the area? 4 The radius of a sphere is decreasing at a constant rate of 6 feet per second. At the : instant when the volume of the sphere is 163 cubic feet, what is the rate of change of the volume? The volume of a sphere can be found with the equation V = 173. Round your answer to three decimal places. 15 ) The volume of a cube is decreasing at a constant rate of 511 cubic meters per minute. At the instant when the volume of the cube is 186 cubic meters, what is the rate of change of the surface area of the cube? Round your answer to three decimal places (if necessary)
