Find Radius
------------------------------------
Radius = Diameter ÷ 2
Radius = 27 ÷ 2
Radius = 13.5 cm
------------------------------------
Find Area
------------------------------------
Area of circle x = πr²
Area of circle x = 3.14 x 13.5²
Area of circle x = 572.265 cm²
------------------------------------
Find Radius
------------------------------------
Radius = Diameter ÷ 2
Radius = 12 ÷ 2
Radius = 6 cm
------------------------------------
Find Area
------------------------------------
Area of circle y = πr²
Area of circle y = 3.14 x 6²
Area of circle y = 113.04 cm²
------------------------------------
Compare the area
------------------------------------
572.265 - 113.04 = 459.23 cm²
------------------------------------------------------------------------
Answer: Circle x is 459.23cm² greater than circle y.
