Answer: what grade is this
Step-by-step explanation:
Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:
Where, r is the radius and 
is the central angle or measure of intercepted arc.
Putting 
in the above formula, we get
Therefore, the exact area of the given sector is 
square meters.

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
