Question

A flower 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

Answer 1

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.
