The amount of soil that the pot can hold is best approximated by calculating for the volume of the cylinder through the equation,
                V = πr²h
We first calculate for the radius, r, given the circumference, C
           C = 2πr;   r = C/2π = 66 in/2(π) = 10.5 in
Then, substituting the known values.Â
               V = π(10.5 in)²(30 in)Â
                 V = 10,390.81 in³
Thus, the volume of the soil is approximately 10,400. The answer is the third set.
