The area of the cross section of the column is 81π
The given parameters are
Circumference, C = π18 meters
The area of the cross section of the column is calculated using the following circle formula
A = π(C/2π)^2
Substitute C = π18 in A = π(C/2π)^2
A = π(π18/2π)^2
Evaluate the quotient
A = π(9)^2
This gives
A = 81π
Hence, the area of the cross section of the column is 81π
