Answer:
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 127.23 cubic inches
3.14 * 3 * 3 * h = 127.23
h = 127.23 / 3*3*3.14
=127.23 * 100 /3*3*3.14*100
=12723/ 3*3*314
= 4241 / 3*314
=4241/ 942
=4.502 inches
h = 4.5 inches
Answer:
50.27
Step-by-step explanation:
A=πr2
A=π×4^2
A=16π
A=50.265482457437
The circle equation in polar coordinates is:
<h3>
How to change the coordinates of the circle equation?</h3>
Here we have the circle equation:
First, we expand it to:
Now we can rewrite it as:
Remember that:
Replacing that, we get:
That is the equation in polar form.
Now, because we can discard the solution r = 0, we can divide both sides by r to get:
To simplify it.

Answer:
105 ft.
Step-by-step explanation:
5 x 12 = 60
So 5 feet is 60 inches.
60 + 3 = 63
That makes the ridge 63 inches long.
When the lion went up the ridge, it traveled 63 inches.
When the lion went back down the ridge, it traveled another 63 inches, totaling 126 inches.
The lion did this 10 times.
126 x 10 = 1260
Divide 1260 by 12 to find the measurement in feet.
1260 ÷ 12 = 105
