Circle A has a diameter of 9 inches, a circumference of 28.26 inches, and an area of 63.585 square inches. The diameter of circle B is 5 inches the circumference is 15.70
inches and the area is 19.625 square inches.

Part A: Using the formula for circumference, solve for the value of pi for each circle

Part B: Use the formula for area and solve for the value of pi for each circle

Part C. What observation can you make about the value of pi for circles A and B?

Is there a picture because i cannot answer it sorry

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
