A conical tent of 56m base diameter requires 3080sqm curved surfacefind it's height?

The area (A) of a cone = πrs where r is the base radius and s is the slant height.

28πs = 3080 : s = 3080/28π = 35.0141 (4dp)

Using Pythagoras, Vertical Height (H) = √(s2 - 282) = √(1225.99

• 784) = √441.99 = 21.02 metres.
