i) write down the area and the perimeter of the circle in terms of r.

*I would go*

*A = ∏r^2*

*A/r^2 = ∏*

*r^2* *= A/**∏*

*r = sqrt(A/∏)*

*P = 2∏r*

*r = P/2∏*

*But not sure if this is right*

ii) find the perimeter of the square in terms of r

iii) using your answer in part ii) state the length of one side of the square in terms of r.

iv) find the area of the square in terms of r

v) find the total area A cm^2 of the circle and the square in terms of r

*i'm unsure how to do these one any help would be greatly appreciated!!*
