Algebraic expression: three more than the product of 17 and v height

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8

Can anyone explain to me how to do this? anything will .
