Step-by-step explanation:
step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.
step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.
 
        
             
        
        
        
Hey!
Hope this helps...

I'm assuming your talking about least to greatest, OR greatest to least.  If so, that's what I'll do...
Least to Greatest: -1, 3, 5, 17, 20
Greatest to Least: 20, 17, 5, 3, -1

1,260 miles all you have to do is 420x3 because Annie drove 3 times faster.

Answer: Choice B</h3>
c^2-2cd+d^2 = (c-d)^2
We can verify this with the following steps
(c-d)^2 = (c-d)(c-d)
(c-d)^2 = c(c-d) - d(c-d)
(c-d)^2 = c^2-cd-cd+d^2
(c-d)^2 = c^2-2cd+d^2
 
        
        
        
He should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents
