Just by estimating, 54% is a little over 1/2 of 168.  You know by that, that neither A or B is close. The real answer is 90.72, so if your instructor wants you to round up, it would be D

C 84. In a quick number crunch your first move is to find 50% of 160 which is 80. The only number above half is 84 so since we need 54% then 84 is the correct answer

The area of a sector of a circle is given by the equation , 3.142S/360 where r is the radius of the circle and S is the angle me
Diano4ka-milaya [45]
Given that the area of the sector is given by:
A=3.142r² S/360
where:
r is the radius 
S is the angle measure of the sector
If Mia solved the equation for S, the equations that she wrote would be found as follows;

From A=3.142r² S/360
making S the subject by first dividing both sides by 3.142r^2 we shall have:
A/3.142r²=S/360
next we multiply both sides by 360
360×A/3.142r²=S/360×360
this will give us
(360A)/(3.142r²)=S
therefore the equation that Mia will get is:
S=(360A)/(3.142r²)
