A shop uses cone-shaped coffee filters in its coffee pots. Each filter has a diameter of 5 inches and a height of 4 inches. What is the volume of the filter? Use 3.14 to approximate pi. Round your answer to the nearest tenth.

Answer:

26.2 inches cubed

Step-by-step explanation:

The volume of a cone is denoted by: [tex]V=\frac{1}{3} \pi r^2h[/tex], where r is the radius and h is the height.

Here, we are given that the diameter is 5. Remember that the radius is simply 1/2 the diameter, so the radius is r = 5/2 = 2.5. We are also given that the height is h = 4. Plug these into the equation:

[tex]V=\frac{1}{3} \pi r^2h[/tex]

[tex]V=\frac{1}{3} *3.14* (2.5^2)*4[/tex] ≈ 26.2

Thus, the volume is about 26.2 inches cubed.

Hope this helps!
