Answer:
[tex]\huge{\text{Circumference = }\boxed{6\pi\ m\approx18.84\ m}}\\\\\huge\text{Area = }\huge\boxed{9\pi\ m^2\approx28.26\ m^2}[/tex]
Step-by-step explanation:
The formula of an area of a circle:
[tex]A=\pi r^2[/tex]
The formula of a circumference of a circle:
[tex]C=2\pi r[/tex]
where r - radius.
We have r = 3m.
Substitute:
[tex]A=\pi(3^2)=\pi(9)=9\pi m^2\\\\C=2\pi(3)=(2)(3)\pi=6\pi m[/tex]
