Question

Use the squares to help you find a reasonable range for the area of the circle. Show your work.

Answer 1

well whats the equation for the area of the circle?

Answer 2

i mean i wld solve it using that. i mean how shld we be solving it?

Answer 3

I'm guessing that they probably have to first add the area of all inscribed squares.

Answer 4

Then they need to add in possible "cut-off" squares as half-area of a unit square.

Answer 5

I found 38 Squares by adding some of the side squares

Answer 6

ohh i found the same thing by just using the equation of the area of circle
so i counted the diameter of the circle and it was 7 so the radius is half of the diameter so its 3.5 so the area of the circle is pi*3.5^2=approx 38.5
