Answer:
option 2
Step-by-step explanation:
A = 2πrh + 2πr²
A = 2πr ( h + r)
2πr ( h + r) = A
(A/2πr) -r =h
A=2πrh +2πr^2
Subtract 2 pi r^2 from each side
A-2πrh=2πrh-2πr^2 +2πr^2
A-2πr^2= 2πrh
Divide each side by 2πr
A/2πr-2πr^2 /2πr = 2πrh/2πr
Sry if it is blurr, is this what you wanted?
Answer is: 4 units ^ 2
Answer: The answer would be 0=0 I think.
they are both 0 since they would not appear on a graph
