Explanation:
The circumference and the are of a circle with radius r
are:
[tex]\begin{gathered} A=\pi r^2 \\ C=2\pi r \end{gathered}[/tex]If we use pi = 3.14 and the radius is 9m:
[tex]A=3.14\cdot(9m)^2=3.14\cdot81m^2=254.34m^2[/tex][tex]C=2\cdot3.14\cdot9m=56.52m[/tex]Answers:
• Area: ,254.34 m²
,• Circumference: ,56.52 m
