I need help with this question

70 GO Figure 6-53 shows a conical
pendulum, in which the bob (the
small object at the lower end of the
cord) moves in a horizontal circle at
constant speed. (The cord sweeps
out a cone as the bob rotates.) The
bob has a mass of 0.040 kg, the
string has length L = 0.90 m and
negligible mass, and the bob follows
a circular path of circumference
0.94 m. What are (a) the tension in
the string and (b) the period of the
motion?
