Radius = Diameter ÷ 2
Radius = 6 ÷ 2
Radius = 3 units

Area = πr²
Area = π (3)²
Area = 28.27 units² (Nearest hundredth)

Find Circumference
----------------------------------------------------------------------------------------------
Circumference = πD
Circumference = π(6)
Circumference = 18.85 units (Nearest hundredth)
