OUTPUT:

unknown shape at (0,0)

Cone at (2,3)

unknown shape at (5,6)

Circle at (0,0) with a radius of 1 has an area of 3.14

Circle at (3,5) with a radius of 2 has an area of 12.56

Circle at (3,6) with a radius of 3 has an area of 28.26

Rectangle at (0,0) with a height of 1 and a width of 1 has an area of 1

Rectangle at (6,7) with a height of 5.4 and a width of 3.2 has an area of 17.28

Rectangle at (8,9) with a height of 2.7 and a width of 8.6 has an area of 23.22
