When the Tang priest recites one spell, the golden cudgel will be shortened by 1%, and when the Tang priest recites ten spells, it will be shortened by 1.6π, so the length of the golden cudgel will become16π-1.6π =/kloc-0.
According to the circumference formula of a circle: πd, using this formula in turn, it can be concluded that a gold hoop with a circumference of 14.4π can be turned into a circle with a diameter of 14.4cm.
The diameter of Wukong's head is 16cm, and the shortened golden hoop is 14.4cm, so the depth of embedding the golden hoop in Wukong's scalp is: (16- 14.4)/2=0.8cm.
A: The Tang Priest recited ten incantations, and the golden hoop was embedded in the Monkey King's scalp, which was 0.8 cm deep.
Pure hand, I hope the landlord will adopt it!
