<u>Answer:</u>
<u>Step-by-step explanation:</u>
The formula for volume of a cylinder is as follows:
where:
• r = radius (? cm)
• h = height (7 cm).
Substituting the values into the formula:
Now solve for 
:
⇒ 
⇒ 
⇒
Given equation : y=ax^2
Taking a to the other side we have, x^2=(1/a)*y
This equation describes a parabola that opens up.
When a is negative, the focus is on the negative y-axis, therefore, the parabola opens down.
The answer is a. down.
If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.
