Answer:
V = 1200π
Step-by-step explanation:
Volume of a cylinder formula:
Let's find the height of the cylinder by multiplying 20 cm by 3/5.
The radius is 1/2 of the diameter, so:
Substitute 12 for h and 10 for r into the volume formula.
Simplify.
- V = π * 100(12)
- V = π * 1200
The volume of a cylinder, in terms of π, is V = 1200π.
Answer:
y = -3
Step-by-step explanation:
The given line is a horizontal line thru -5 on the y-axis.
Your line is parallel to y = -5, hence is also a horizontal line and passes thru (2, -3). Since -3 is the y-coordinate of that point, y = -3 is the equation of the line you are looking for.
Answer:
m = 1
Step-by-step explanation:
Lines b and c are parallel and thus have the same slope. We need only find the slope of b or the slope of c, and will then have both.
5
The slope of b is m = ---------- = 1
5
The answer to this is 39 and 27
