Step-by-step explanation:

Upper and lower surfaces of the cylinder:

\pi r^{2} =9\pi \\S=2*9\pi =18\pi

Side area of the cylinder:

S=sh=\pi dh=6\pi *3*8=144\pi

The total area:

S=114\pi +18\pi =162\pi =162*3.14=508.68

1. Find the values of X and Y.
Andrei [34K]
156 and (14y+30) are opposite angles so they are the same. You can use this information to put them into an equation to solve;

14y+30 = 156
You want you the the y's alone, so you subtract 30 from each side.
14y = 126
Then divide each side by 14 to get what just 1 y is.
y = 9

Then to find what the other pair of opposite angle add up to subtract 156x2 from 360
156x2 = 312             360-312 = 48

Halve 48 to get the sum of just one of the opposite angles
48/2 = 24
Now you know that 3x = 24.       Solve this equation
                                 x = 8
