Step-by-step explanation:
Volume of a cylinder = πr²h
Solve for r
V = π * r² * h
r² = V/πh
Find the square root of both sides
r = √V/πh
If height = 6 meters and volume = 300 cubic meters. Find r
r = √V/πh
= √(300/3.14*6)
= √(300/18.84)
= √15.923566878980
r = 3.9904344223381
Approximately,
r = 4 meters
The most direct form to graph a line, is to find two points of it and connect them with a line.
Here we have:

Let's find the point where x = 0. To do this, we replace the x in the equation by 0:

We have our first point: (0, -6)
Next let's find the point where y = 0. Again, we replace y in by 0 in the equation:

We have our second point, (3, 0)
Now all we have to do is plot the points (0, -6) and (3, 0) in the plane, and connect them with a line, and then the line is graphed
The line should look like this:
Answer:
23 and 7
Step-by-step explanation:
Multiply 23 and 7 to get 161. Subtract 7 from 23 and get 16
Answer:
125.6 sq ft.
Step-by-step explanation:
To find the Surface Area of the cylinder, we will need to solve for the area of both bases and the rectangle around the cylinder. We can do this by:
------------------------------
Area of bases: (
)


Since we have two bases, we can simply multiply by 2, giving us:
12.56×2= 25.12
-------------------------------
Area of the rectangle: (
)

12.56×8= 100.48
Add these two together, giving us:
100.48+25.12= 125.6 sq ft.
