*see attachment for the dimensions of the cone given.

Answer:

7.9 in³

Explanation:

Given:

Height of cone = 4 in.

Diameter of cone = 2¾ in

Radius (r) = ½ of 2¾ = 1.375 in

Required:

Volume of the cup

Solution:

Volume of the cup = volume of a cone

Volume of a cone = ⅓πr²h

Plug in the values of π, r and h into the formula.

Volume = ⅓*3.14*1.375²*4 = 7.9 in³ (approximated to the nearest tenth)
