Calculation path
Calculate total right-cone surface area. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
Calculation path
A=pi r(r+sqrt(r^2+h^2))
What you receive
What you receive
- Surface area in square units from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
Use one consistent dataset or geometric scale and verify assumptions before interpreting rounded results.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
