Find Distance and Height

A surveillance satellite circles Earth at a height of h miles above the surface. Suppose that d is the distance, IN MILES, on the surface of the Earth that can be seen from the satellite.

NOTE: The radius of Earth is 3960 miles.

(a) If d is to be 2500 miles, how high must the satellite orbit above Earth?

(b) If the satellite orbits at a height of 300 miles, what distance d on the surface can be seen?
