Answer:
h = 7 in
LA = 42π in²
SA = 60π in²
Step-by-step explanation:
Use the appropriate formula with the numbers you know, and solve for the number you need to know.
V = πr²h
h = V/(πr²) = (63π in³)/(π(3 in)²)
h = 7 in
__
LA = 2πrh
LA = 2π(3 in)(7 in)
LA = 42π in²
__
SA = 2πr(r +h)
SA = 2π(3 in)(3 in +7 in)
SA = 60π in²

To see if its right:
y*y+y*9-9*y-9*9
y^2+9y-9y-81
y^2-9^2
Since f(x) = -3x + 2, the slope of f(x) is greater than the slope of g(x).
Hence, the answer is (D).
