Puys please help me with this question :

A city has a circular wall surrounding it. The wall has 4 gates located at the east, west, north and south points. A temple stands at a distance of 1 km to the east of the east gate outside the city. It can be seen by a person standing sqrt(3) km directly to the north of the west gate, but if any closer to the west gate, the wall obstructs his view of the temple. Find the radius of the wall which surrounds the city (in km).

A)1 B)2 C)3 D)4.

2) for y=5, x^3-4x^2 = 100^2*96 only one power of 3

so the highest term must have only one power of 3. and the minimum power of 2 is 3 for y=3....so it should be 24

Didnt understad this part..could u pls elaborate..
