Hollow Cylinder Area Calculator

Hollow Cylinder Area Calculation

Cylinder radius value (r1)

m

Cylinder radius value (r2)

m

Area (A)

m²

This calculator calculates the area (a) using cylinder radius value (r1), cylinder radius value (r2) values.

Formula:

Area (A):
A1 = π r1²
A2 = π r2²
A = A1 - A2
