Question

example 1 find perimeter, circumference, and area think about it! how can you use the coordinate grid to check your answer? each square on the grid represents square unit. you could estimate the number of squares the shape to determine the approximate

Explanation:

Step1: Count full - squares

Count the number of full - squares inside the circle.

Step2: Combine partial squares

Combine partial squares to form whole - like squares. For example, two half - squares can be considered as one whole square.

Step3: Sum up squares

Add the number of full - squares and the equivalent whole - squares from partial squares to get the estimated number of squares.

Answer:

(The actual number of squares will depend on the counting result from the above steps. Since the grid is not provided with a clear - cut count in the image, we can't give a specific numerical answer. But the process is as described above.)
