Answer: 16

Step-by-step explanation:

From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.

The probability of picking a blue marker will be: = 5/25 = 1/5

Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:

= 1/5 × 80

= 16 times

FInd the volume of the cylinder in terms of Pi.
Luba_88 [7]

The formula for the area of a cylinder is \pir^{2}×h

First, we do not have to worry about pi because we are leaving our answer in terms of it so we can move on to the radius squared.

The radius is halfway across a circle so our radius would be 4 and we have to square that and we will get a product of 16.

Lastly, we have to multiply 16 by 8 because 8 is the height of the cylinder

16 × 8 = 128

Therefore, the volume of the cylinder would be 128\pi in.³
