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 - r2) A = π(122 - 52) A = π(144 - 25) A = 119π ~ 373.8495
Calculate Equation (assume radius of (0,0):
25 ≤ x2 + y2 ≤ 144
What is the Answer?
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. This calculator has 2 inputs.
