The circle inside the large square below has an area of 47.4 cm2.
Calculate the area of the large square. Note that the circle passes right through a number of grid intersection points.
Heres the help the professor gave
C^2 = A^2 + B^2
D= sqrt(x^2 + b^2)
D = 2sqrt(A/pi)
The Attempt at a Solution
4a tall and 1a long
d = sqrt((1a)^2 + (4a)^2)
d = sqrt(1a + 16a)
stuck here I am not sure what else to do
