Answer:
It is irrational, & cannot be written as a fraction.
Step-by-step explanation:
will give you a very odd number when plugged into the calculator.
1.414213562
With our knowledge of rational vs. irrational numbers, we know that means has to be irrational because it is not a whole number, not an integer, & cannot be condensed into a fraction.
Any time you see a number that isn't a perfect square in a square root, it might be best to guess it is irrational.
Always plug it into a calculator (if possible) to check!
Hope this helps. :)

Answer:
The area of the sector is 3pi/2
Step-by-step explanation:
A sector is that part of a circle bounded by 2 radii and an arc
The circle has an area of 9 pi with a central angle of 60 degrees.
Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.
Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.
Thus, the area of the sector is one-sixth the area of the circle.
The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi
