An annulus has a large radius (R) of 12 and a small radius (r) of 5, calculate the Area (A) and equation of the annulus

A = π(12

A = π(144 - 25)

A =

25 ≤ x^{2} + y^{2} ≤ 144

25 ≤ x^{2} + y^{2} ≤ 144

Calculates the area of an annulus and the equation of the annulus using the radius of the large and small concentric circles.
