Please help asap Number 2 and 3

Step-by-step explanation:

2)  r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

                                        = 2 * 3.14 * 8 * 8

                                       = 401.92 cm²

Midlle part = h * πd

                 = 6 * 3.14 * 16

                = 301.44 cm²

Total = 401.92 + 301.44

        =        703.36 cm²

3) Area of front and back =

Area of bottom = length * breadth

                           = 12* 3

                          = 36 cm²

Area of left =  12 * 4

                  = 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
