1. What is Radius at Area Centroid of Solid of Revolution?

The Radius at Area Centroid of Solid of Revolution is the horizontal distance from the centroidal point with respect to area under the revolving curve to the axis of rotation of the Solid of Revolution.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Radius\ at\ Area\ Centroid = \frac{LSA + ((r_{Top} + r_{Bottom})^2 \times \pi)}{2 \times \pi \times A_{Curve} \times \frac{SA}{V}} \]

Where:

\( LSA \) — Lateral Surface Area of Solid of Revolution (m²)
\( r_{Top} \) — Top Radius of Solid of Revolution (m)
\( r_{Bottom} \) — Bottom Radius of Solid of Revolution (m)
\( A_{Curve} \) — Area under Curve Solid of Revolution (m²)
\( \frac{SA}{V} \) — Surface to Volume Ratio of Solid of Revolution (1/m)
\( \pi \) — Archimedes' constant (approximately 3.14159)
