Answer:
18
Step-by-step explanation:
(5/6)x – 4 = 11
(5/6)x = 11 + 4
(5/6)x = 15
5x = 15×6 = 90
x = 90/5 = 18
Answer: 527.79 m²
Step-by-step explanation:
formula is A = 2πrh + 2πr²
A = 2π x 4 x 17 + 2π x 4²
A = 527.79 m²

Answer:
90 ft
Step-by-step explanation:
Times the length by the width of one side: 6 x 3= 18
Times 18 by 4 to get the surface area of the 4 rectangular sides: 18 x 4= 72
Times 3 by 3 to get the bottoms surface area: 9
Times 9 by 2 to get both the top and bottoms surface area: 18
Add 72+18 to get the total surface area: 90 ft
