Is This A Good Or Bad Thing?
We need to find the angle (rounded to the nearest whole degree) of a circle that would represent the percent of students taking mathematics.
Since a complete turn around the circle has 360º, we have the following proportion:
<em>Number of students Angle</em>
734 360º
442 x
Then, cross multiplying the above values, we obtain:

<em>Answer</em>: 217º
Answer:
The length of the arc shown in red is 
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to

we have

substitute


step 2
Find the length of the arc in red
Remember that the length of the circumference subtends a central angle of 360 degrees
so
by proportion find the length of the arc by a central angle of 110 degrees

Simplify

You substitute the variables with the number into the equations and set the equations equal to each other and solve ( systems of equations )
