An annulus has large radius 12 and small radius 5 Image to Crop

An annulus has a large radius (R) of 12

It has a small radius (r) of 5

Calculate the Area and equation

Annulus Area Formula:

A = π(R2 - r2)

Plug in A = 12 and r = 5

A = π(122 - 52)

A = π(144 - 25)

A = 119π ~ 373.8495

Annulus Equation

Assume a radius of (0,0)

r2 ≤ x2 + y2 ≤ R2

25 ≤ x2 + y2 ≤ 144

What is the Answer?

25 ≤ x2 + y2 ≤ 144
