Question

A sandcastle mold is in the shape of a cylinder with a diameter of 6 inches and a height of 8 inches. To the nearest cubic inch, how much sand will fit in the sandcastle mold? Explain how you determined your answer . In your explanation, use the word pi instead of the symbol pi

Answer 1

To evaluate for the amount of sand that can fit in the sandcastle, we obtain the volume of the castle.
V=πr²h
From the information:
r=6/2=3 inches
h=8 inches
thus the volume will be:
V=π×3²×8
V=72pi
Hence the amount of sand required will be 72pi in³
