Answer:
h = 16 inches
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2 pi r^2 + 2 pi rh
We know the surface area and the radius
1206.4 = 2 ( 3.14) * 8^2 + 2 * 3.14 * 8 *h
1206.4 = 401.92+50.24h
Subtract 401.92 from each side
1206.4-401.92 = 401.92-401.92+50.24h
804.48=50.24h
Divide each side by 50.24
804.48/50.24 =50.24h/50.24
16.01273885=h
Answer:
4x+64
Step-by-step explanation:
Perimeter is the sum of all sides so you add all of the expressions together. Then combine like terms, x+x+2x, and 14+14+36. Combine them and you get 4x+64.
Answer:
Yes, no two ordered pairs in this list has the same second element.
Step-by-step explanation:
The function is a relation that associates to different elements 
and 
different elements 
and 
Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}
So,
Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."
