The amplitude is 2. Amplitude is always positive and is the number in front of sin, cos, tan, csc, sec, cot
2+34=4(x+5)
distribute
2+34 = 4x+20
combine like terms
36 = 4x+20
subtract 20 from each side
16 = 4x
divide by 4
4 = x
Answer: x=4
The surface area would be 26.5487 m².
The surface area of a cylinder is equal to the area of the circles at both ends, added to the area of the rectangular portion in the middle. The rectangle in the middle has a width equal to the circumference of the circle and a length equal to the height of the cylinder.
The circumference of a circle is given by C = πd, and the area of the circles is given by A=πr².
Since the height is in meters, we will convert it to cm. 3.5 m = 350 cm.
The diameter is 190 cm, so the radius is 190/2 = 95 cm.
This gives us:
SA = 3.14(190)(350)+2(3.14)(95)²
= 208810 + 56677 = 265487 cm² = 26.5487 m²
