⦁ One cup has a diameter of 2 in. and a height of 4 in. How many cups of water must Carissa scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number

Answer 1

Carissa must use about 452 cups to scoop out the entire sink

Explanation:

The volume of the sink is 3,617 inches^3

The volume of the cup is 8 inches^3

So we divide 3,617 by 8

3,617 ÷ 8 = 452.125

Rounded to the nearest cup, we need 452 cups to scoop out the sink
