Question:
What is the area of the sector? Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal rounded to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the values of radius and central angle are not given.
However, I'll answer the question using the attached figure.
From the attached figure, the radius is 3 unit and the central angle is 120 degrees
The area of a sector is calculated as thus;
Where 
represents the central angle and r represents the radius
By substituting 
and r = 3
becomes
square units
Solving further to leave answer as a decimal; we have to substitute 3.14 for 
So, becomes
square units
Hence, the area of the sector in the attached figure is 
or 9.42 square units
Folding a paper will make it thickness become double from it before.
Unfolded paper has 1 thickness
1 times folded paper has 2 thickness
2 times folded paper has 4 thickness
3 times folded paper has 8 thickness
From here it is clear that the pattern is
. SInce the paper is 0.1mm, then the function would be:
f(n)=
x 0.1mm
Answer:
64 textbooks
Step-by-step explanation:
the first two teachers had 21 students each that's 21+21=42
the other teacher had 22 students so apparently all the textbooks handed to the students are,21+21+22=64
Answer: -10
Step-by-step explanation:
It is -10 because you have to switch the order of operations to get negative.
Hope it helps!
