<h3>
Answer: B) 19</h3>
Explanation:
There are 20 choices for president, and 20-1 = 19 choices for vice president. You count down by 1 each time you fill a seat. So that means you'll have 19-1 = 18 choices for the third seat, and 18-1 = 17 choices for the fourth seat.
I first found the slope of the line graphed. So i took 2 points and found the slope. They were (2,0) and (0,-3). The slope was 3/2. I then flipped it and added a negative because your looking for the perpendicular line. That was -2/3.
I took the formula y1-y=m(x1-x) and put in -2/3 as m and y1 as 2 and x1 as -1. You plug those into the equation and solve for y.
I got B for the answer

Answer:
4cm
Step-by-step explanation:
The volume of the cylinder is the product of the area of the base and the height. In mathematical equation, this can be written as,
V = πr²h
where V is volume, r is the radius, and h is the height.
Substituting the known values from the given,
176π cm³ = πr²(11 cm)
