Answer:
V = πr²h
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
where V is the volume, r is the radius, and h is the height of the cylinder.
_____
<em>Comment on the formula</em>
This is a specific version of the formula for any sort of "prism" with parallel bases and a uniform cross section (parallel to the bases). The volume of such a figure is computed as ...
V = Bh
where B is the area of the base and h is the perpendicular distance between the parallel bases. Here, the base is a circle, so has area formula ...
B = πr²
Filling this into the volume formula gives ...
V = πr²h . . . . . as above
The length of pendulum is 2.485 feet
<h3><u><em>
Solution:</em></u></h3>
Given that,
The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth
<u><em>Therefore, the given formula is:</em></u>

We have to find the length of pendulum that makes one full swing in 1.75 seconds
So the modify the given equation to find "L"

Substitute T = 1.75 seconds and 

Thus length of pendulum is 2.485 feet approximately

It costs $ 30240 to stain floor of the entire room
<em><u>Solution:</u></em>
<em><u>Given that,</u></em>
Sgt. Merritt has bought a house now that his tour of duty is up
He wants to stain the wood floors of the living room, which measure 18 x 14
Therefore,
length = 18 yards
Width = 14 yards
<h3><u>Find the area:</u></h3>

Thus area of wood floors is 252 square yards
<h3><u>How much will it cost to stain floor of the entire room?</u></h3>
The stain costs $120 per square yard

Thus it costs $ 30240 to stain floor of the entire room
