Daniel has a cylindrical container with a diameter of 10 inches. He fills it with sand to a depth of 6 inches. What is the volume, to the nearest cubic inch, of the sand in Daniel’s container?
The formula is 3.14 x radius^2 x height, so let's plug in the values. The radius is half the diameter, and the height is 6, so the equation is 3.14 x 5^2 x 6. 5^2 = 25, and 3.14 x 25 = 78.5. 78.5 x 6 = 471, so D is your answer. :)
