Acone shaped paper cup is 10 cm high and has a diameter of 8 cm using this cup about how many servings can you get from one liter of water ?

Volume of cone = 1/3 × pie × radius^2 × height
Volume of one cone = 1/3 × pie × (8/2)^2 × 10
= 1/3 × 16 × 10 × pie
= 160/3 × pie
{Approximately}~~~ 167.6cm^3 (rounded to nearest 1 decimal place)

1 litre = 1000cm^3

Number of servings = 1000 ÷ 167.6
{Approximately}~~~ 6 servings

Hope this helps! :)
