Circle A has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. The diameter of circle B is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches.

Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)

Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)

Part C: What observation can you make about the value of pi for circles A and B? (2 points)

Step-by-step explanation:

The Diameter by two to get the radius while you plug in your other values. You would then get these two equations:

  1) 21.98=2pi(3.5)   2) 18.84=2pi(3)

  21.98/(3.5)2=pi     18.84/(3)2=pi

   pi=12.56         pi= 12.56

Part B: The formula for Area is A=pi(r^2). Since we already have our radius, we can plug in all the information we have to solve for pi. The equations should be:

   1) 38.465=pi(3.5^2)     2) 28.26=pi(3^2)

    38.465/(3.5^2)=pi      28.26/(3^2) =pi

       pi= 3.14                pi= 3.14

Part C: The observation to be made is to find the pi of a circle's area is going to equal to pi=3.14.
