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. V = π(10.5 in)²(30 in) V = 10,390.81 in³ Thus, the volume of the soil is approximately 10,400. The answer is the third set.
