Answer:
SA = 680 units^2
V =1200 unit^3
Step-by-step explanation:
If the radius is 5 then the diameter is 2r = 2*5 = 10
The height would remain the same
Surface area of a prism is given by
SA = 2 (lw+lh+hw)
l =d = 10 w = d = 10 h = 12
SA = 2 ( 10*10 + 10 * 12+ 12* 10)
SA = 2( 100+120+120)
SA = 2(340)
SA = 680 units^2
V = l*w*h = 10*10*12 =1200 unit^3

Hi there!
I will help you answering the questions, if you do not understand what I'm working about, you can ask me on comment section.
<h3>Number 1</h3>First of all, we need to multiple the separated function.
So the right answer is <u>A</u>
━━━━━━━━━━━━━━━━━
<h3>Number 2</h3>the graph has four zeros at :
- -4
- -2/3
- 0
- 9
After that we make them equal with 0, here is the thing:
x = -a is equal with x + a = 0
So we can conclude that :
- -4 → x + 4 = 0
- -2/3 → 3x + 2 = 0
- 0 → x = 0
- 9 → x - 9 = 0
Then we substitute them to a function :
x(x + 4)(3x + 2)(x - 9) = 0
3x⁴ - 13x³ - 118x² - 72x = 0
Then we looking on the option which one is equal with the answer above.
The right answer is <u>B</u>
