Find the total surface area of the capped cylinder.

2 times the area of the base would be 2[pi*(3 cm)^2, or 18pi.

The circumference of the base is C = 2pi*r, which here is 6pi.
The area of the sides is C times height, or 6pi*(11 cm) = 66pi cm^2

Add this to the 18pi cm^2 previously found.

Total area of cylinder, including top and bottom, is 84 cm^2.

(NEED DONE QUICK) Two angles are supplementary. One of the angles measures 4(2x+9) and the other angle measures 2(4x-8) what is

Studentka2010 [4]

Answer:

$x=10$

Step-by-step explanation:

Supplementary angles are angles equal to 180°.

Therefore:

$4(2x+9)+2(4x-8)=180$

Now that we have our equation, let's distribute the $4$ and the $2$ into the parentheses they are next to:

$8x+36+8x-16=180$

Combine like terms:

$16x+20=180$

Subtract $20$ from both sides of the equation:

$16x=160$

Divide by the coefficient of $x$ , which is $16$ :

$x=10$

~

Check your work by substituting $10$ into one of the equations above:

$8(10)+36+8(10)-16=180$

$80+36+80-16=180$

$180=180$

It's correct!
