Open calculator ↗MEET THE FIGURE
A right circular cylinder, explained.
A right circular cylinder has two congruent parallel circular bases whose centres are joined by an axis perpendicular to both base planes. The calculators model the closed solid, including both bases in total surface area.

More than a formula.
The lateral surface can be flattened into a rectangle without stretching.
Total surface area here includes two bases. Slanted cylinders and open containers need different surface models.
