Answer:
The formula for the volume of a cylinder is r^2piH.
Step-by-step explanation:
The process is to find the radius and square it, the radius is half of the top or bottom circle. And then you can get a calculator and multiply it by pi, or 3.14, or 3.141592653... Then you multiply it by the height. So the answer for this cylinder 200pi, or 628.3185307, you can round however you need to

Answer:
A. maximum value at 30
Step-by-step explanation:
−x² + 10x + 5
First, factor out the leading coefficient from the first two terms:
-1 (x² − 10x) + 5
Take half of the next coefficient, square it, then add and subtract the result.
(-10/2)² = 25
-1 (x² − 10x + 25 − 25) + 5
-1 (x² − 10x + 25) + 25 + 5
-1 (x² − 10x + 25) + 30
Factor the perfect square.
-1 (x − 5)² + 30
The equation is now in vertex form. This is a downwards parabola with a vertex at (5, 30). Since the parabola points down, the vertex is a maximum.
500 miles in 2 minutes means you divide 500 by 2 to find what half of 500 is since you do half of 1,
so the answer is
250 m/ min
