Answer:
h = 21.5cm.
Step-by-step explanation:
<em>Step one:</em> Simplify the volume.
220.16 x (pi) = 691.65cm^3.
<em>Step two:</em> Isolate h.
Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.
Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.
<em>Step three:</em> Solve for h.
691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.
To illustrate this, please check the diagram below.

Answer:
The probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license is 0.32.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = a fisher at Clearwater Park had a fishing license
<em>Y</em> = a fisher at Mountain View Park had a fishing license
The two events are independent.
The information provided is:
n (X) = 48
n (X') = 32
n (Y) = 72
n (Y') = 18
Then,
N (X) = n (X) + n (X')
= 48 + 32
= 80
N (Y) = n (Y) + n (Y')
= 72 + 18
= 90
Compute the probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license as follows:
Thus, the probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license is 0.32.
