5+3+-9+3=2 and then the varibles so the answer is 2 cubed
        
             
        
        
        
Answer:
a) 9*π or approx 28.26
b) ∡CRB=100°
Step-by-step explanation:
As known for secants crossing each other inside the circle is coorect the following:
BR*RD=AR*RC
=> 3*RD=4*4.5
RD=6
The diameter of the circle with center P is BD=BR+RD=3+6=9
So the radius of the circle is D/2=9/2=4.5
As known the circumference of any circle can be calculated as
C=2*π*r  , where r is the circle's  radius
So C=2*4.5*π=9*π= approx   3.14*9=28.26
b) ∡CRB=∡ARD= (arcBC+arcAD),  where arcBC and arcAD smaller arcs
BD is the circle's  diameter, so arc BD=180°
So arcBC=180°-arcCOD=180°-100°=80°
Similarly arcBD=180°
arcAD=180°-arcBSA=180°-60°=120°
∡CRB= (80°+120°)/2=100°

Answer:
<u><em>It has gone -160 miles.</em></u>
Step-by-step explanation:
To find the answer we will <em>multiply -40 by 4 hours</em>, and we get<em> -160 miles</em>.  Therefore, the car has <em>traveled -160 miles</em>.
