An annulus has large radius 12 and small radius 5
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
Calculate Area (A):
A = π(R2
A = π(122
A = π(144 - 25)
A = 119π
Calculate Equation (assume radius of (0,0):
25 ≤ x2 + y2 ≤ 144
How does the Annulus Calculator work?
Calculates the area of an annulus and the equation of the annulus using the radius of the large and small concentric circles.
