8.1

Step-by-step explanation:

1) There are 360 degrees in a circle.  Therefore, the arc measure of PQ would be 360-(73+150+65)= 72.  

2) The intercepted arc is the same measure as the central, making it 72.  Therefore it takes up 72/360 of a circle or 1/5.  

3) To find the measure of it, you would find 1/5 of the circumference.  C=2πr . C=2(3.14)(6.48)≈ 40.7 .

4) 1/5 of the circumference would be (40.7)/(5)≈8.1

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
