Circumference = [tex]2 \pi r[/tex]
6.28 = [tex]2 \pi r[/tex]
r = 1

Area = [tex]\pi r^2[/tex]
Area = [tex]\pi (1)[/tex]
Area = 3.14

Hope that helps :)

Area of a circle = [tex] \pi r^{2} [/tex]
Circumference of a circle = [tex]2 \pi r[/tex] or [tex] \pi d[/tex]

Circumference = [tex] \pi d[/tex] = 6.28
d = 2
r = 1

Area = [tex] \pi (1)^{2} [/tex] = 3.14
