The circumfrence of a circle is \pi  d
diamter is 2r ( Two times the radius ) 
So you would now have
5 \pi
\pi = 3.14

(3.14)(5) = 15.7 
The answer is B, 15.7

Anna [14]

Answer:

Step-by-step explanation:

First, take the 50% off the sales price:

($48)*(-0.50) = -$24.

($48 - $24) = $24 sale price.

Tax on $24 is ($24)*(0.05) = $1.20

Answer:

-1/3

Step-by-step explanation:

Use the formula, (y2 - y1)/(x2 - x1).  In this case, there is a negative slope.  

Start from point, (1, 9) and go to point (4, 8).  

Use the formula:

(y2 - y1)/(x2 - x1)

Y2 = 8

Y1 = 4

X2 = 9

X1 = 1

(8 - 9)/(4 - 1) = -1/3

Therefore, the slope is -1/3
