Answer:
Step-by-step explanation:
V, r, h are the volume, radius, and height, respectively.
V = πr²h = 9πr²
The only error in your previous answers was that you forgot the π.
if r = 1, V = 9π1² = 9π ≅ 28 in³
if r = 2, V = 9π2² = 36π ≅ 113 in³
if r = 3, V = 9π3² = 81π ≅ 254 in³
Do you mean checking your work? In that case it would be 9*20.
