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.

2 miles:10 seconds
? miles: 120 seconds
120 divided by 10 =12
12 x 2 =24
Answer:
Below in bold.
Step-by-step explanation:
5x - 3y = 1
3x- y = 5 Multiply this equation by -3:
-9x + 3y = -15 Now add this equation to the first equation:
-4x = -14
x = -14/-4 = 3.5.
Now substitute for x in equation 1:
5(3.5) - 3y = 1
-3y = 1 - 17.5
-3y = -16.5
y = 5.5.
