The answer is 81/8
Alternative Forms:
10 1/8 or 10.125
Area of sector=fraction of sector times area of circle
fraction of sector=degrees/360
and area of circle=pir^2
so
hold a sec, we have the wiper on the outside, so we want to find the outside ring thing
do
area big sector-area small sector
or even better
(degrees/360) times (area big-areasmall)
big is 10
small is 4 (10-6=4)
areabig=10^2 times pi or 100pi
areasmall=4^2 times pi or 16pi
areabig-areasmall=100pi-16pi=84pi
then find the fraction
84pi times (150/360)=35pi square inches

The coefficient of x is the slope of the line , So the slope of the above equation is -3 .

Remember from now on ,
Product of multiplying the slopes of two lines which are perpendicular to each other , is -1 .
Thus ;

m is the slope of the line which we want.

Negatives simplifies

Divide sides by 3

We have following equation to find the point-slope form of the linear functions :

x(0) and y(0) are the coordinates of the point which the line passed through.


Add sides 8

Done....
