I think the answer is
352.47
Answer:
1.2 cm
Step-by-step explanation:
Quadrilateral circumscribing a circle is a quadrangle whose sides are tangent to a circle inside it (see attached diagram).
The area of circumscribed quadrilateral is
where 
is semi-perimeter and r is radius of inscribed circle.
In your case, 
If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so
so
Now
First find the slope, so subtract the y1 and 2 then same thing with x. -7-1=y. -2-(-3)=x. y is -8 and x is 1. divide -8 and 1. which gives you -8. SLOPE is -8. THE FORMULA for slope intercept form is Mx+B=y first insert the numbers then solve. need any more help use the app socratic and photo math
For 10 hours of job Gerald earns 8*10=80$
For 11 hours Gerald earns 8*10+9n. n - number of working hours over 10 hours.
if Gerald work 16 hours, then he work 6 hours after 10, so n=6
8*10+9*6=80+54=134$
Answer: Gerald earns 134$ if he works 16 hours in one week.
Sorry for my bad English pls:)
