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. help me
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?

Step-by-step explanation:

Write down your information-

Circle A: 7in Diameter with a circumference of 21.98 inches and an area of 38.465 square inches

Circle B: : 6in Diameter with a circumference of 18.84 inches and an area of 28.26 square inches

Part A: The formula for circumference is c=2pi(r). We then want to divide diameter by two to get 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 in all the information that 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 obserservation to be made is find the pi of the area of a circle is going to equal to pi=3.14.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
