Answer:

33.6π mm²

Step-by-step explanation:

The ratio of areas between two similar shapes is the square of the ratio of the lengths of the shapes.

A₁ / A₂ = (L₁ / L₂)²

Given that A₂ = 210π mm², L₁ = 24π mm, and L₂ = 60π mm:

A₁ / 210π = (24π / 60π)²

A₁ = 210π (24π / 60π)²

A₁ = 33.6π

The area of the smaller cylinder is 33.6π mm².
