Which graph represents the solution of x2 + (y – 2)2 < 36 and y2 > 8x?

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

Just tell me how to set up the equation.
