First, let's find the area of the circle of the first cylinder. To do this, we square the radius and multiply by 3.14.
3²=9
9×3.14=28.26
Now we multiply by our height of 49 cm to see how much water there is.
28.26×49=1384.74
Now, let's find the area of the circle of the 7 cm cylinder.
7²=49
49×3.14=153.86
Now, we will take our liquid amount (volume) and divide by this circle amount (base) to find the number of centimeters of height of the water column.
1384.74÷153.86=9
So, the height of our water column will be 9 cm.
Have a wonderful day and keep on learning! :D
Answer:
1/2
Step-by-step explanation:
7/12 of the punch was left.
There is 12/12 (whole) of the punch Dave is holding, then when he spills 5/12, that is 12/12 - 5/12 which equals 7/12. Did this help?
