A cone-shaped paperweight has a diameter of 3 inches and a height of 5 inches.
What is the volume of the paperweight?
Enter your answer as a decimal in the box. Use 3.14 for pi.
volume of cone = (1/3) * pi * radius2 * height
radius = diameter/2
radius = 3/2 inches
volume of cone = (1/3) * pi * (3/2)2 * 5
= (1/3) * pi * (9/4) * 5
= (15/4)pi
≈ (15/4)(3.14) = 11.775 cubic inches
