\Use the squares to help you find a reasonable range for the area of the circle. Show your work.
A circle is placed on a grid of squares, each one unit by one unit. A square that is 5 units by 5 units fits completely inside the circle. The circle fits completely inside a square that is 9 units on each side.

Best ResponseYou've already chosen the best response.1Well, since a 25 units^2 square fits completely inside the circle, it has to be greater than 25 units^2
