Answer:
V=97.08
Step-by-step explanation:
The formula for the volume of a cone is V= 1/3 pi (r)^2 (h)
To find the radius divide the diameter by 2. 6/2=3
Plugin: V=1/3 pi(3)^2(10.3)=97.08
See how there are two rectangle prisms? Find the area of both of them separate, and then add the two answers together.
Hope this helps!!
Answer:
9.0586 OR
9.06
Step-by-step explanation:
IDK, used fusion 360
If the number on the bottom of the fraction is 8 times the size
of the number on top, then the fraction is equal to 1/8 .
Examples:
100 / 800
20 / 160
8 / 64
We start with

and wish to write it as

First, pull 2 out from the first two terms:

Let’s look at what is in parenthesis. In the final form this needs to be a perfect square. Right now we have

and we can obtain -10x by adding -5x and -5x. That is, we can build the following perfect square:

The “problem” with what we just did is that we added to what was given. Let’s put the expression together. We have

and when we multiply that out it does not give us what we started with. It gives us

So you see our expression is not right. It should have a -53 but instead has a -3. So to correct it we need to subtract another 50.
We do this as follows:

which gives us the final expression we seek:

If you multiply this out you will get the exact expression we were given. This means that:
a = 2
d = -5
e = -103
We are asked for the sum of a, d and e which is 2 + (-5) + (-103) = -106
