Aflower pot, in the shape of a cylinder, l has a circumference of 66 in. and a height of 30 in.
which estimate best approximates the amount of soil the pot can hold?
3600 in³
10,400 in³
43,600 in³
98,000 in³

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.
