(03.06 MC)Luke filled the glasses shown below completely with water. The total amount of water that Luke poured into the glasses
Usimov [2.4K]

Glass 1 is a right circular cylinder and Glass 2 is a cone. The total volume of water in both the glasses is 100 centimeters cubed. Some given dimensions are:

Right Circular Cylinder:

diameter = 5, thus radius is half of that, radius = cm

height = we need to find

(Note: Formula for volume, V, is )

Cone:

diameter = 6, thus radius is half of that, radius =  cm

height = 5.2 cm

(Note: Formula for volume, V, is )

Now adding the 2 volumes and equating to 100, and then solving for h will give us our answer (we will use π as 3.14). Let's do this.

pir^2+1/3pir^2h=100

(3.14)(2.5)^2h+1/3(3.14)(3)^2(5.2)=100

19.625h+48.984=100

19.625h=51.016

h=51.016/19.625=2.60 cm

Hence height of glass 1 is 2.60

2.63 cm
