#color(blue)(PC = 12.97 " Corrected to 2 decimal points"#

Explanation:

#"Given : OC = 30, AP = 24.7, To find PC"#

#"Radius " R = OC = OA = OB = 30#

#AP = PB = 24.7#

Using Pythagoras theorem,

In Right triangle OAP, #OP^2 = OA^2 - AP^2#

#OP = sqrt(30^2 - 24.7^2) = 17.03#

#PC = OC - OP = 30 - 17.03 = 12.97#
