Answer:

m = 9.3

Step-by-step explanation:

you want to solve for m

to get it alone you need to add 4.2 to both sides

m - 4.2 + 4.2 = 5.1 + 4.2 The 4.2 on one side cancel out solving for m

The measure of central angle QRS is radians. What is the area of the shaded sector? 36 72 144 324

The picture in the attached figure

we know that

the angle measurement of central angle QRS is less than pi radians

area of the circle=pi*r²
for r=18 units
area of the circle=pi*18²------> 324*pi units²
area of the half of a circle=324*pi/2-----> 162*pi units²
area of a quarter of a circle=324*pi/4----> 81*pi units²

<span>analyzing the graph we can say that the shaded area is smaller than the area of the middle of a circle but it is larger than the area of a quarter of a circle
</span>so
the area of the shaded sector < 162*pi units²
and
the area of the shaded sector > 81*pi units²

therefore
the answer must be 144*pi units²
