Explaining an arithmetic issue

Include the top radius, bottom radius, slant height, units and expected result. A copied plan keeps the canonical millimetre dimensions and assumptions together. If the issue concerns printing, first measure the calibration line and record whether the print software used actual size or fit-to-page. Do not send unnecessary personal details or account credentials.

The guide explains sector development, the equal-radius cylinder branch and SVG approximation. Read Privacy for email handling, or return to the calculator.
