Need help on this question please help! A 20-ounce box of cereal costs $3.20. A 12-ounce box of cereal costs $1.80. Which box of cereal is the better buy?

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
