The volume of the cone is
one-third of the volume of the cylinder which is equal to the product of area
of the base and the height. The equation is,
<span> V = (1/3)(pi)(r^2)h </span>
Dividing both sides of the
equation by (1/3)(pi)(h) will give us,
<span> 3V/(pi)(h) = r^2</span>
Taking the square-root of
both sides,
<span> r = sqrt(3V/(pi)(h))</span>
The vertices coordinates following a reflection along the y-axis are S(-6,6), T(2,6), U(2,0), V(-6,0).
<h3>What is reflection?</h3>
A reflection point is created when a figure is constructed around a single point known as the point of reflection or the figure's centre. There is an exact opposite point on the other side of each point in the figure. Under the point of reflection, the figure's size and shape are unaltered.
Given points are p ( 8,-2 ) Q(8,5) R( 4,-2 )
The reflection of the points
P (8,-2) = P (-8, 2)
Q (8,5) = Q (-8, -5)
R (4,-2) = R (-4, 2)
Therefore, the coordinates of the vertices after a reflection across the Y-axis are P (-8, 2) Q (-2, 6) R (-2, 0)

Answer:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean
Step-by-step explanation:
Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
