1) find the mean,
   20+10+30+20+50+30+40+20/8= 27.5
2) Find the distance of each value from that mean
   20- 7.5
   10- 17.5
   30- 2.5
   20-7.5
   50- 22.5
   30- 2.5
   40- 12.5
   20- 7.5
3) Find the mean of those distances
   7.5+17.5+2.5+7.5+22.5+2.5+12.5+7.5/8=10

The Mean absolute deviation for this data set is 10.

The volume of a cone is 36 min 3. What is the volume of a cylinder with the same base and height as the cone?

Rina8888 [55]

Answer: LAST OPTION

Step-by-step explanation:

The formula for calculate the volume of a cone is:

$V_{co}=\frac{1}{3}r^2h\pi$

Where r is the radius and h is the height.

The formula for calculate the volume of a cylinder is:

$V_{cy}=r^2h\pi$

Where r is the radius and h is the height.

As you can see, the difference between the the formulas is that <em>r²hπ</em> of the cone is divided by 3. Therefore, if you know the volume of the cone and you know that cylinder has the same base and height as the cone, you have to multiply the volume of the cone by 3.

Therefore, the result is:

$_{cy}=36in^3*3=108in^3$
