Question

the circumference of 9 m high conical tent is 24 m find its curved surface area.


help me!!!​

Answer 1

180π sq.m

Step-by-step explanation:

Circumference = 2πr = 24π m

where r is base radius, we get r = 12 m from the above relation.

slant height l = begin mathsize 12px style square root of r squared plus h squared space end root space equals space square root of 12 squared plus 9 squared end root space equals space 15 space m end style

curved surface area = πrl = π×12×15 = 180π sq.m
