Simon:75+15w
 
        
             
        
        
        
Answer:
r equals StartFraction C Over 2 pi EndFraction
Step-by-step explanation:
we know that
The circumference of a circle is equal to

where
r is the radius of the circle
Solve for r
That means -----> isolate the variable r
Divide by 2π both sides

Simplify right side

Rewrite

so
r equals StartFraction C Over 2 pi EndFraction
 
        
                    
             
        
        
        
Rhombus -> 2 equivalent obtuse angles, 2 equivalent acute angles 
vs. 
Rectangle -> 4 equivalent right angles. 
        
                    
             
        
        
        
Answer: 9/100
Step-by-step explanation:
Probability of people own a cat:
P(cat)=30/100=0.3
Probability of people own a bird:
P(bird)=3/100=0.03
Probability of both own a cat and a bird
P(cat and bird)=(30/100) × (3/100)
 =90/1000=9/100=9%
