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)

Answer 1

Hi

Answer 2

So we would need to formulas
Circumference=2piR
Area=Pi R^2

Answer 3

So can u go on

Answer 4

so for part a it says that you have to find the value of pi for the circle. isn't pi always 3.14. @diamondboy

Answer 5

hello? @diamondboy

Answer 6

thats a good question

Answer 7

but maybe they want an evaluated value but go ahead anyways
