Answer:
S = π( 2(9) + 2(3)(14))
Step-by-step explanation:
Here we are to select which of the options best describe the equation that could be used to find the surface area of the cylinder.
Mathematically,
the surface area of a cylinder can be calculated using the formula
S = 2 π r^2 + 2 π rh
from the question, we have r as d/2 = 6/2 = 3cm and h = 14cm
We plug these two values into the equation above
Thus, we have
S = 2 * π * 3^2 + 2 * π * 3 * 14
S = π( 2(9) + 2(3)(14))
First, subtract 10h from 15h so the variables are on the same side. You get:
5h+30<-45
Then, you can solve the inequality like any other equation. Subtract 30 from -45:
5h<-75
Finally, divide -75 by 5 to get your answer:
h<-15
Answer:
Step-by-step explanation:
(When c=the amount of caffeine and p=the amount of pepsi)
c = 3p
The unit rate is 3 mg of caffeine per oz of pepsi
Step-by-step explanation:
Adding 3 to both sides, we get
Dividing both sides by 2, we get
