Answer:
c. 198π units²
Step-by-step explanation:
We have to find the surface area of a cylinder.
We know that surface area of a cylinder= 2πrh+2πr²
where r is the radius
and h is the height of the cylinder.
here h=2 units and r=9 units
Surface area= 2π×9×2+2π×9×9
= 198π units²
Hence, correct option is:
c. 198π units²

Answer:
x=3
Step-by-step explanation:
Figure ABCD is a rectangle. In rectangles, <u>opposite sides are equal</u>. In the figure, BC and AD are opposite of each other, therefore their side lengths are equal. The side lengths are given: BC=9x-6, and AD=3x+12. Write this as an equation:
- 9x-6=3x+12
- 9x-3x-6=3x-3x+12 (Subtract 3x from each side of the equation)
- 6x-6=12
- 6x-6+6=12+6 (Add 6 to each side of the equation)
- 6x=18
- x=3 (Divide each side by 6)
please let me know if this is wrong, hope it helps :)
X/2+7=14
14/2= 7
7+7=14
