Answer:

you need the formula for the cone , Korc

Step-by-step explanation:

formula for cone = \frac{1}{3}*π*r^{2}*h

they tell us that the diameter is 8 so  r = 4

and that h = 9

volume of cone = \frac{1}{3}*π*4^{2}*9

VoC = 150.796

VoC = 150.8  ( to the nearest 10th)

"What is the area of the polygon given below?<br> "
nikklg [1K]
Area = 525

A_1 = L X W = 9 * 28 = 252
A_2 = L X W = 18 * 14 = 252
A_3 = L X W = 7 * 3 = 21

A = A_1 + A_2 + A_3 = 252 + 252 + 21 = 525

Find the average rate of change of the function defined by the following table X -2,2,6,10 Y -5,35,75,115
hjlf

Answer:

The slope is 10 (y =10x +15)

Step-by-step explanation:

When using two coordinates to find the slope of a linear function, I choose (-2,-5) and (2,35) *but you can choose any two.

The formula for finding the slope is y-y divided by x-x.

so... (35)-(-5)=40        NOTE: I did 35 minus -5 but you can also do -5 minus 35.

2-(-2)=4                           But just remember to do it the same order for

                                    subtracting the x coordinates.

40/4=10
