Answer:
Volume of a cylinder.
Step-by-step explanation:
The given equation is :

Where
r is the radius
h is the height
This equation is used to find the volume of a cylinder.
For example, a cylinder having radius of 7 units and height of 10 units, its volume will be :

So, the given equation is used to find the volume of a cylinder.
Increasing function is any function whose value increases with respect to an increase in the variables.
Decreasing function is any function whose values are decreases with respect to an increase in the variables.
Without rounding to the nearest tenth, it would be 7.28. Rounding it would give you with an answer of 7.3 with rounding.
A=$2.49/15oz≈$0.166/oz (17 cents per ounce to nearest cent)
B=$3.32/20oz=$0.166/oz (same as above)
So A=B, they both has the same price per ounce.
