I need help the answer correct will get a prize

2260.8cm^2

Step-by-step explanation:

Area of cross - section x 2 = 3.14 x r^2 x 2= 3.14 x 144 x 2= 904.32cm^2

Area of curved surface = pi x d x 18 = 3.14 x 24 x 18 = 1356.48cm^2

Total surface area = 1356.48 + 904.32 = 2260.8 cm^2

Its given that the total bill = 60(1 + x)

                                          = 60 + 60x

So, its clear that the cost of meal is 60 and the percentage of tips is x.

Also, number of friends = (total cost/cost per meal)

                                        = 1 + x

Hence, the correct match is:

1) - c)

2) - a)

3) - b)
