Question

Find the circumference and area of a circle with a diameter of 22 inches.

Answer 1

Answer:

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

Step-by-step explanation:

Diameter of the circle=$22\;inches$

$Radius=\dfrac{22}{2} =11\;inches$

Circumference of a circle:

            $=2\times \pi \times r$

            $=2\times \pi \times 11\\\\=22\pi \;inches$

Area of the circle:

                  $=\pi \times r^2$

                 $=\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2$
