Circumference: 18.84 m
Area: 28.26[tex]m^{2}[/tex]
Explanation
For circumference, use the formula [tex]\pi[/tex]*d, where d=the diameter(the radius times 2).
For area, use the formula [tex]\pi[/tex][tex]r^{2}[/tex], where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi([tex]\pi[/tex]) is Delicious(diameter) and Apple(area) [tex]\pi[/tex] [tex]r^{2}[/tex]("are too")
