Question

Mrs. McDonnell is making 25 paper cones to fill with popcorn for her daughter's birthday party. 4 inches 7 inches Find the volume of one paper cone if the diameter is 4 inches and the height is 7 inches. Round your answer to the nearest cubic inch.

Answer 1

The volume of one cone would be 29 in³.

The formula for the volume of a cone is V=(1/3)πr²h.  Substituting our information we have:

V=(1/3)(3.14)(4/2)²(7)

We divide the diameter by 2 because the radius is half of the diameter.  This gives us:
V=1/3(3.14)(28) = 29.306 ≈ 29in³
