Formula: Area=pi times radius squared (the official one is A=pi symbol times r for radius squared
Radius=diameter divided by 2
3.6/2=1.8
1.8 squared=3.24
A=3.14 x 3.24
Area=10.1736 meters squared
Final Answer: Radius: 1.8 meters, Unit of measure: meters, Area: 10.1736 meters squared (round to whatever place your teacher wants you to)
