Answer:
AAS
Step-by-step explanation:
Assuming you're concerned with interest rate problems, r is generally involved in something like the formula ...
... i = prt
So, r will have the units of ...
... r = i/(pt) = (dollars)/(dollars·year) = 1/year
That is, r is <em>(some fraction) per year</em>.
_____
Often, the fraction is expressed as a percentage. The fraction will be unitless (as percentages are), leaving the units of r as year⁻¹.
Answer:
110.25π 
Step-by-step explanation:
The can is a circular cylinder and has the formula for the volume to be
V = 
r = 3.5 and h = 11
Since the paint is now 2 in. from the top of the can, then there are 9 in. left in the can, which means there is 9/11 of the total volume in the can.
Therefore, 
we get V = (9/11)(12.25)(11)π
= 110.25π 
You multiply 65 to the x and negative 5
