Mr. James has cylindrical beakers that measure 4 inches in diameter and are 9 inches high. What is the volume contained within the beakers? Use 3.14 for pi. Round your answer to the nearest hundredth.
56.52 cubic inches
100.34 cubic inches
113.04 cubic inches
226.08 cubic inches
To find the volume of the cylindrical beaker, we can use the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height.
The diameter of the beaker is 4 inches, so the radius is half of the diameter, which is 4/2 = 2 inches.
Plugging in the values into the formula:
V = 3.14 * 2^2 * 9
= 3.14 * 4 * 9
= 113.04 cubic inches
Therefore, the volume contained within the beaker is 113.04 cubic inches.
