Answer:
First option: True.
Step-by-step explanation:
To know if the volume of this cylinder is 496.21 ft³, you need to use the formula for calculate the volume of a cylinder:

Where "r" is the radius and "h" is the height.
You can observe in the figure that the radius of the cylinder is 4.5 feet and the height is 7.8 feet.
Then, knowing this, you can substitute these values into the formula.
Therefore, the volume of this cylinder is:

Then the answer is: True.
The answer is B.4940. I found the picture of the pyramid u forgot to post. The volume for pyramid is lwh/3
Answer:
its red
Step-by-step explanation:
math. lol
The way we can find out the unit rate (also known as the <em><u>SLOPE</u></em>) is by using the table as coordinates!
The slope formula is 
With the table, the TIME column can be "x"
The DISTANCE column can be "y"
____________________________
As coordinates, it would look like...
(0,0)
(20, 25)
(30, 37.5) and so on!
_____________________________
All we need to do now is use 2 of these coordinates and plug them into the slope formula in their correct places to find the unit rate!
Example:
solve!
= 12.5/10 ⇒ 1.25 ( or 5/4 in fraction form)
3.305
+1.7
5.005
Line up the decimal points and add like you usually would add.
5.005 is the answer.
