81
Step-by-step explanation:
total number of people voting = 216
number of people who voted yes =

The formula for the surface area is given and as follows.
SA = (2)(3.14)(r^2) + (2)(3.14)(r)(h)
The radius of the cylinder is 4 inches and the height is 9 inches. Using the given values, we can plug them into the formula and solve for the surface area from there.
SA = (2)(3.14)(4^2) + (2)(3.14)(4)(9)
SA = (6.28)(16) + (6.28)(36)
SA = 100.48 + 226.08
SA = 326.56 in^2
Hope this helps!! :)
Answer:
9
Step-by-step explanation:
The whole line is 180 degrees. First, you have to set up an equation. This equation would be 3x+94+x+36+2x-4=180. You can then combine like terms. The equation would now be 6x+126=180. Then subtract 126 from both sides of the equation. This would give you 6x=54. Divide 6x on both sides. The answer is 9.
