So we know the formula for circumference is C= πrd. And Circumference is the distance around a circle. 

Example: C= circumference 
C= 6.28 can u find the  circles area :? 
 Step 1: divide 6.28 by 3.14 as the formula says.

Step 2 : after u divided u get 2 which is the diameter. and u divide the diameter by 2 because we are trying to get the radius because the formula for the circles area is 
A= πr ^2

r = radius 
r= 1 

so what is 3.14 times 1
= 3.14

so 3.14 is the answer 

I hope this helped u understand.

Answer:

Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.

Rubys market sells smoked meats by the pound the prices for several different meals are shown in the table.
vichka [17]
Question 1: <span>how much more does 1 1/4 pounds of beef cost than 1 1/4 pounds of turkey?

$4.25/pound (beef) / 4 = $1.06 per 1/4 lb = $4.25 + $1.06 = $5.31 per 1 1/4 lb
$2.85/pound (turkey) / 4 = $0.71 per 1/4 lb = $2.85 + $0.71 = $3.56 per 1 1/4 lb

$5.31 - $3.56  = $1.75 (the beef is more expensive by this much compared to the 1 1/4 lb of turkey) 

Question 2: </span><span>question 2. brad has 10 dollars to spend at ruby's. He orders 1/2 pound of sausage and 1 1/4 pounds of chicken. How much money will he brad have after he pays for this order?

$3.25 / 2 = $1.62 per 1/2 pound of sausage 
$2.50 / 4 = $0.62 per 1/4 lb of chicken + $2.50 = $3.13 per 1 1/4 lb of chicken

$1.62 (1/2 lb sausage) + $3.13 (1 1/4 lb chicken) =$4.75
$10 (budget) - $4.75 (total expense)  = $5.25 (Brad will have this much left from his budget)</span>

Part A: y<4x-8 is a dotted line intercepting the y-axis at -8, and increasing by a value of 4, with shading bellow the line. The Second equation (which I can't fully type out) is a solid line intercepting the y-axis at 5,decreasing by a value of -5/2, and has shading above the line.

Part B: It does not because the point (5,-8) doesn't appear where the shaded areas meet.
