no it wasn't it was c, check values inside and outside of the region and u will find that b does not work
bro i tried all options c is not right, im pretty sure you get like the radius being larger than a point on the circle from z=0 ( i might be wrong dont know tbh seeing i didnt even get the double angle out for 15 ii lol)

Isn't the circle generated by B in the wrong quadrant? Maybe my cartesian expansion had an error, it looked wrong so i went D

nah just did it again, i used i and another number cant remember, also a and d are disprove by subbing in i and then b is wrong by subbing in a point in the shaded region

no way I got 10/10 mc by an educated guess (I had no clue for any). “ahh yeah, acc decreasing, must mean a.v is decreasing”. Free CHICKEN dude
