Answer:


Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2

Explanation:

Diameter of the circle=
22\;inches


Radius=(22)/(2) =11\;inches

Circumference of a circle:


=2* \pi * r


=2* \pi * 11\\\\=22\pi \;inches

Area of the circle:


=\pi * r^2


=\pi * 11* 11\\\\=121* \pi \\\\=121\pi \;inches^2
