Answer:


Circumference=10\pi \;inches\\\\Area=25\pi \,inches^2

Explanation:

Diameter of the circle=
10\;inches


Radius=(10)/(2)=5\;inches

Circumference of a circle =
2* \pi * r

As,


\pi =(22)/(7) =3.14

In terms of '
\pi':

Circumference:


=2* \pi * 5\\\\=10\pi \,inches

Area of a circle=
\pi * r^2


=\pi *( 5 * 5)\\\\=25\pi \;inches^2
