The circumference of the circle is 22π.
What is the area of the circle?
The area of the circle is given by;
[tex]\rm Area \ of \ circle=\pi r^2[/tex]
The area of a circle is 121π in².
The circumference of the circle is;
[tex]\rm Circumference =2\pi r[/tex]
The area of the circle is;
[tex]\rm Area \ of \ circle=\pi r^2\\\\121\pi =\pi r^2\\\\r^2=121\\\\r^2=11^2\\\\r=11[/tex]
The circumference of the circle is;
[tex]\rm Circumference =2\pi r\\\\Circumference =2\pi \times 11 \\\\Circumference =22\pi[/tex]
Hence, the circumference of the circle is 22π.
