HELP ME PLZ.
i need to Find the surface area and volume

A ≈ 494.80

V = 827.02

Step-by-step explanation:

height ( h ) = 13 mm

radius ( r )  = = 4.5 mm

Surface area  =

                      = 2π(4.5)(13) + 2π(4.5)

                      ≈ 494.80

Volume =

             =

             = 827.02

im alright what do you need

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
