A drinking glass is shaped like a cylinder with a height of 5 in. and a diameter of 3 in. Maeva adds 25 spherical pieces of ice to the glass. The pieces of ice each have a diameter of 1.1 in.
How many cubic inches of water can Maeva add to fill the glass to the rim? Use 3.14 to approximate pi and round your answer to one decimal place.
first find volume of glass find volume of ice subtract
cylinder area=height times are of base
height=5 area of base=circle=pi times radius^2 diameter=2radius diameter/2=radius 3/2=radius=1.5
pi=aprox 3.14 3.14 times 1.5^2=7.065 7.065 times 5=35.325=volume of glass
25 spereical ice volume of shqere=4/3 times pi timers r^3 diameter/2=r 1.1/2=0.55 4/3 times 3.14 times 0.55^3=0.696557=1 ice multiply by 25 17.4139 subtract 35.325-17.4139=17.9111 round to one decimal place 17.9
