In Step 1, the radius should be found by multiplying the diameter by 2.
In Step 2, the formula 2pi r should be used to find the area of the circle.
In Step 3, the resulting area should be in terms of pi
In Step 4, the units of the resulting volume should be cm^2
Whenever we are given with the diameter of any such figure ,
to find the radius , we divide the diameter by 2.
We know that
Diameter = 2 * radius
or
Radius = Diameter /2
,
In the question it says the in first step that
the radius should be found by multiplying the diameter by 2
, this is the first error
It should be that
the radius should be found by dividing the diameter by 2

Answer:
Number line graph with closed circle on 20 and shading to the right or c
Step-by-step explanation:
This is the best answer because you start of at 20 dollars and need to continue collecting money till you have 160 dollars.
Answer:
The 3rd one
Step-by-step explanation:
You have already collected $20. You need at least $160, but having even more money would be great. You need $160, but any number to the right of 160 would be even better as your goal.

vertex= ?
axis line of symmetry equation?
Answer:
The vertex is at ( 3.5, -0.25)
and the axis of symmetry is x = 3.5.
Step-by-step explanation:
Convert to vertex form:
y = x^2 - 7x + 12
y = (x - 3.5)^2 - 3.5^2 + 12
y = (x - 3.5)^2 - 0.25
y = (x - 3.5)^2 - 0.25.
So the vertex is at ( 3.5, -0.25)
and
the axis of symmetry is x = 3.5.
The vertex of the parabola y = x² - 7x + 12 is at (3.5,-0.25) and the equation of the axis of symmetry is x = 3.5.
The given quadratic equation is y = x² - 7x + 12. To determine the vertex and the equation of the axis of symmetry, we need to first find the x-coordinate of the vertex, which is determined by the formula -b/2a. Here in our equation, a = 1 (coefficient of x²) and b = -7 (coefficient of x), so x = -(-7)/(2*1) = 3.5.
The x-coordinate of the vertex is thus 3.5. Now, to get the y-coordinate of the vertex, we substitute x = 3.5 into our equation, so y = (3.5)² - 7*(3.5) + 12 = -0.25. Therefore, the vertex of the parabola is at (3.5,-0.25). The line of symmetry of a parabola always passes through the vertex, so the equation of the axis of symmetry is x = 3.5.
