Answer:
113
Explanation:
The formula for volume of a cylinder is π
h
Fill in with your values:
π = 3.14
r = 3
h = 4
3.14
4 = 3.14(9)4 = 3.14(36) = 113.04
Round down to 113
This is a system of equations, meaning you find the value of one variable and substitute it into the other equation
if y=-x^2-4x+23 we can put that into the second equation for y
This gives us 2x+(-x^2-4x+23)=15
Lets simplify this and set it equal to 0 by moving the 15 over
-x^2-2x+8=0
This gets us x=-4, 2
Lets try plugging both those back into our first equation and see what value of y we get
y=-(-4^2)-4(-4)+23; y=23
y=-(2^2)-4(2)+23; y=11
So you get two sets of solutions
(-4,23) and (2,11)
