-------------------------------------------
Find Diameter :
-------------------------------------------
Circumference = πD
32.7 = πD
D = 32.7 ÷ π
D = 10.41cm

-------------------------------------------
Find Radius :
-------------------------------------------
Radius = Diameter ÷ 2
Radius = 10.41 ÷ 2
Radius = 5.21 cm

-------------------------------------------
Find Area :
-------------------------------------------
Area = πr²
Area = π (5.21)²
Area = 85.11 cm²

-------------------------------------------
Answer : Area = 85.11cm²
