Question

Q.2. How many square metres of canvas is required for a conical tent whose height is 3.5m and the radius of the base is 12m ?​

Answer 1

Answer:

For the conical tent ,

h= 3.5 m

r= 12m

slant height , l= √r²+h²= √144+12.25= √156.25= 12.5m

then , curved surface area of the tent =πrl= 22/7× 12× 12.5= 471.43 sq.m.

required area of canvas= 471.43 m²
