A point is chosen at random in the circle. What percent of the time will the point be in the shaded region ? Round to the nearest tenth of a percent .

Ibelieve the total for the tip could be $21.90

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
