The difference between the volume of cone and the volume of a cylinder?

Sergeu [11.5K]3 years ago
4 0

Solution:

we have been asked to find

The difference between the volume of cone and the volume of a cylinder?

As we know that the volume of the cone is given by the formula

V=\frac{1}{3} \pi r^2h\\ \\ \text{where h= height of cone, r=radius } \\

And the volume of the Cylinder is given by the formula

V= \pi r^2h\\ \\ \text{where h=Height, r=radius}\\

The difference between the volume of cone and the volume of a cylinder can be calculated as below

Difference=\frac{1}{3}  \pi r^2h-\pi r^2h=-\frac{2}{3}\pi r^2h

The relationship between the number of gallons of water in a tank and number of hours is proportional. One point on the line mod
Over [174]

Answer:

Step-by-step explanation:

I am assuming the tank starts empty. It means that in 1 hour the tank has half that water, or 3600 gallons. And the good thing of lines passing through 0.0 is that the value at 1 IS the slope we need. ie 3600.

At this point it's easy to find that if in 2 hours it filled 1/10th of the tank, in 20 hours the tank will be full.

Caitlin has 4 and 3/4 lb of place use 1 1/10 pound to make a cup and another 2 pounds to make a jar how many pounds are left
g100num [7]
We know that
4 3/4---------> (4*4+3)/4----------> 19/4
1 1/10-----------> (10*1+1)/10----> 11/10

[pounds left]=[(19/4)-(11/10)-(2)]----> (10*19-4*11-40*2)/40
=(190-44-80)/40-------> 66/40---------> 1.65 pounds
1.65-----> 1 65/100--------> 1 13/20 pounds

the answer is 1.65 pounds  (1 13/20 pounds)

Is the statement (3^5)^4 = (3^4)^5 true? Explain your reasoning.
Evgesh-ka [11]

Answer:

We use the power rule of exponents to find out that both sides of the equation equal 3^20 (or 3486784401).

Step-by-step explanation:

For this example, we can just use a calculator and find out that both (3^5)^4 and (3^4)^5 are the same value. But how do we know this algebraically?

When dealing with exponents, we must have a good understanding of the properties of exponents before doing any calculations.

For this example, I recognize that the power rule of exponents is being used:

(a^{m})^{n}  = a^{m*n}

So let's apply this rule to the given equation.

(3^5)^4 = (3^4)^5

3^(5*4) = 3^(4*5)

3^20 = 3^20

Now we know both sides of the equation equal 3^20 (or 3486784401).
