Step-by-step explanation:
To find the exact volume of a cylinder, you must remember the rule - π r2 h
If 6 inches was the base (radius from the center of the cylinder to the edge) and 9 inches was the height, the equation would look like this -
π (6 squared in) (9 in)
Remember that the radius is squared so the equation would then look like
π (36 in) (9in)
Now you multiply 36 and 9 which would give you 324, then your equation would look like this
324 π
The final step is to multiply 324 by π which would be the volume of a cylinder.
Using proportions, it is found that the value of a is of 3.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, a 180º angle has a measure of
radians. What is the measure of a 540º angle? The <em>rule of three</em> is given by:
180º -
rad.
540º - x
rad.
Applying cross multiplication:
180x = 540.
x = 540/180 = 3.
The value of a is of 3.

Answer:
x
Step-by-step explanation:
We need to solve this equation by graphing. We need to find what roots will make our equation equal zero. This is the same as drawing a line

and see what points intercepts both graphs.
According to the graph above, one root are between 0 and 0.5 and the other are between 4 and 4.5.
We can find it actual value by solving it


Apply Quadratic Formula, we get

and

Which gives us approximately
x=4.27 and 0.23
