You see a star close to the central mass moving with a speed v (in metres per second). The apparent radius of its circular orbit is a (measured in radians), and it takes a time p to complete each orbit (in seconds) Derive an equation for the distance from Zing to the central mass. Explicitly indicate multiplication with a symbol, and with the letters "pi".
