in detail i want d answer
area of canvas required = Curved Surface Area of the cone CSA of cone = π*r*l so we first need to find l l = sqroot(r^2 + h^2) = sqroot[(12m)^2 + (3.5m)^2] = sqroot[ 144 m^2 + 12.25 m^2]

471 square meters
l = 12.5 m so CSA = 22/7 * 12m * 12.5 m = 471.43 sqmtr
thxs to alllllllllllllllll
answer is 471.4
Hmm don't we consider the base?
@vengeance921 we r not given that the base is also canvas. for the language above we just need to find the CSA
True, thanks.
Thanks, except for adding the base your calc was also right
u hav done dat knw and u deleted it
