Step-by-step explanation:

the area of :

1) inside surface = (3.14× 1.25²)+(3.14×2.5×1.5)

= 4.90625 + 11.775 = 16.68125 m²

2) upper side surface= (3.14 × (1.35²-1.25²))

= 3.14× (1.8225-1.5625)= 3.14×0.26=0.8164m²

3) lateral surface= 3.14×2.7×1.6=13.5648m²

the total amount of vinyl required for the spa =

16.68125+0.8164+13.5648 = 31.06245 m²

Given OL and ON m PLEASE HELP !!!
il63 [147K]

Answer:

∠MON = 57°

Step-by-step explanation:

Given that OL and ON are perpendicular lines then ∠LON = 90° and

∠LOM + ∠MON = 90, substitute values

3x - 15 + 5x - 23 = 90, that is

8x - 38 = 90 ( add 38 to both sides )

8x = 128 ( divide both sides by 8 )

x = 16

Hence

∠MON = 5x - 23 = (5 × 16) - 23 = 80 - 23 = 57°
