A water cup is in the shape of the cone. The diameter of the cup is 3 inches and the height is 6 inches. What is the volume of water the cup could hold? Use 3.14 for pi. Enter your answer, as a decimal, in the box. ____ in3
Accepted Solution
A:
V = volume of cone r = radius h = height
Formula: V = pi*r^2*h
Plug in r = 1.5 (since d = 3 is the diameter, you cut it in half to get the radius) and h = 6
V = pi*r^2*h V = pi*1.5^2*6 V = 13.5*pi V = 13.5*3.14 V = 42.39
