Circumference = πD

------------------------------------------------------------------------
Given that the circumference is 75cm, find Diameter:
------------------------------------------------------------------------
πD = 75
D = 75 ÷ 3.14
D = 23,89 cm

------------------------------------
Find Radius:
------------------------------------
Radius = Diameter ÷ 2
Radius = 23.89 ÷ 2 
Radius = 11.94 cm

------------------------------------
Find Surface Area:
------------------------------------
Area = πr²
Area = 3.14 x 11.94²
Area = 447.65 cm²

------------------------------------
Answer: 447.65cm²
