Area of circle=π(R)^2
=π(13)^2
=π169 cm^2
area of circle=π(r)^2
=π(11)^2
=π121 cm^2
are of circular ring= π169-π121
= π(169-121)
=π48
=150.72 cm^2 since, π=3.14
=π(13)^2
=π169 cm^2
area of circle=π(r)^2
=π(11)^2
=π121 cm^2
are of circular ring= π169-π121
= π(169-121)
=π48
=150.72 cm^2 since, π=3.14
