3. (20 points) Write a complete C++ program that asks the user to enter the necessary information about the cylinder, calculate the volume in a function (named as calculate_vol, using reference to pass the volume value out), then display the cylinder volume in main function. The volume of cylinder is:

Vol_Cylinder = πr²h

Where π is 3.14159265, r is the radius, and h is the height.

Question 3: Run this program for different choices of the dipole length.

Consider a wind turbine comprised of two blades, with a radius of 63 ft., which delivers maximum power when the wind speed is above 16 knots (18.4 mph). The wind turbine is designed to produce 135 hp with an efficiency of 74%. The rotor is designed to operate at a constant speed of 45 rpm in winds over 5 knots (5.8 mph) by controlling system load and adjusting blade angles.

Estimate the blade speed and power coefficient for the maximum power condition.
