Answer:
4 pitches
Step-by-step explanation:
if a cylinder with height 9 inches and radius r is filled with water, it can fill a certain pitcher. how many of these pitchers can a cylinder with height 9 inches and radius 2r fill? explain how you know.
Solution:
The volume of a cylinder is given by:
V = πr²h;
where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.
A cylinder with height 9 inches and radius r can fill a certain pitcher. Therefore the volume of the cylinder is:
V = πr²h = πr²(9) = 9πr²
V = volume of pitcher = volume of cylinder with radius r = 9πr²
For a cylinder with height 9 inches and radius 2r its volume is:
V2 = πr²h = π(2r)²(9) = 36πr²
Therefore, the number of pitchers a cylinder with height 9 inches and radius 2r can fill is:
number of pitches = 36πr² / 9πr² = 4
Therefore a cylinder with height 9 inches and radius 2r can fill 4 pitches.
Answer:
The domain is all real numbers and the range is all real numbers as-well.
As x approaches infinity, so does y.
As x approaches -infinity, so does y.
Answer:
for number one, look at the screenshot attached, that should help
Step-by-step explanation:
no
no because maynor rode 2 miles every 4 minutes and paul rode 3 miles every 4 minutes. not the same
2p=pe^0.067t
2=e^0.067t
t=(log(2)/log(e))/0.067
T==10.3 years
