For circle area = π * r *r
=> r = square root of Area/ π
=> so circumference = 2 * π * r
= 2 * π* sqrt ( Area / π)
= 2 * sqrt (Area * π)
here sqrt means square root.
=> r = square root of Area/ π
=> so circumference = 2 * π * r
= 2 * π* sqrt ( Area / π)
= 2 * sqrt (Area * π)
here sqrt means square root.
