Respuesta :

Answer:

  [tex]Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2[/tex]

Step-by-step explanation:

Diameter of the circle=[tex]22\;inches[/tex]

[tex]Radius=\dfrac{22}{2} =11\;inches[/tex]

Circumference of a circle:

            [tex]=2\times \pi \times r[/tex]

            [tex]=2\times \pi \times 11\\\\=22\pi \;inches[/tex]

Area of the circle:

                  [tex]=\pi \times r^2[/tex]

                 [tex]=\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2[/tex]
