To figure out this problem you need to find the area of the cylinder A= pi r^2 *h
Then find the area of the cone 1/3*pi*r^2 *h
Subtract the two answers
Answer:
c
Step-by-step explanation:
To find the maximum point, differentiate:
D' = -8p +160
Set to zero and solve for p:
D' = 0
⇒ -8p +160 = 0
⇒ 8p = 160
⇒ p = 20
Input p = 20 into the original equation to find D:
D = -4(20)² + 160(20) -310 = 1290
Therefore, the price is $20 and the maximum number of drills is 1,290

Answer:
Step-by-step explanation:
For this you just have to make an equation and in order to do that you have to know that all these angles will equal 180°. Now we can write it out.
Now we combine like terms:
Add the 9 on both sides:
Divide the 21 on both sides:
