0.43 should be the answer.
Answer:
243π inches
Step-by-step explanation:
The volume of a cylinder is πr^2 * h
r = 9
h = 3
81π * 3 = 243π
If you want at least 3 pounds of hamburgers, then $6 is enough to buy those 3 pounds of hamburgers. If you ONLY buy 3 Pounds, then you also have enough for 4 pounds of chicken. $3 a pound x 4 = $12. You have 2 dollars left to spare, which means you can buy another pound of hamburgers. So 4 pounds each are able to be purchased.
For this case, what you should see is where the graph cuts the x-axis.
Notice that the graph cuts to the x axis in three different points.
Then the value of x that is in the domain of the function in this case is:
x = 1
For this value of x the function is zero.
Answer:
x = 1
Volume = 1/3 * area of base * height
= 1/3 * 11^2 * 12
= 484 cm^3
