The radius of a conical tent is \(20 \ m\) and the height is \(21 \ m\). Find the length of the canvas used to make the tent if the width of the rectangular canvas is \(3 \ m\)?
Answer:
The slant height of the conical tent is \(m\).
The curved surface area of the tent is given by sq. units.
The curved surface area of the tent is \(m^2\)
The length of the canvas is \(m\).
