Answer
44
Step-by-step explanation:
R = C/(2*Pi).
So, in order to find the radius from the circumference, you use the formula R = C/(2*Pi). In other words, just divide the circumference by 2 times pi.
 
        
             
        
        
        
40% = 32/x
Rewrite using a decimal
.40 = 32 / x
Multiply both sides by x
.40x = 32
Divide both sides by .40
x = 32 / .40
x = 80
Write the full fraction
32/80
Answer 32/80
        
             
        
        
        
So your present value is 7750. this is what you have now. they give you the intesrest rate which is 4% and how the amount of year is 5. 
recall the formula for a compounded continously is
P×e^(r×t)
the answer is 7750×e^(.04×5)
        
             
        
        
        
The number in the photo should be the answer but the problem might just be that your question was worded incorrectly.
 
        
        
        
Answer:
1.75
c
+
2.25
a
=
1083.00
now we still know, that 
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
 so: 
c
=
120
