It should be noted that 21.46% of the square remains uncovered when the circular tin is placed on the square.
How to calculate the percentageradius = side/2 = (side x sqrt(2))/2sqrt(2) = diagonal/2sqrt(2)
The area of the circular tin is pi times the radius squared, or:
Area of tin = pi x (diagonal/2sqrt(2))^2 = pi x (diagonal^2/8)
The area of the square is simply the side squared:
Area of square = side^2 = diagonal^2/2
Uncovered percentage = [(Area of square - Area of tin)/Area of square] x 100%
Uncovered percentage = [(diagonal^2/2) - (pi x diagonal^2/8)]/(diagonal^2/2) x 100%
Uncovered percentage = (4 - pi)/4 x 100% ≈ 21.46%

If the plant grew 17 inches and each inch is equivalent to 2.5 cm, you would have to multiply 17 and 2.5.
17x2.5=42.5
And 42.5 is approximately 43.
