Question

how many square metres of canvas is required for a conical tent whose height is 12 m and the radius of whose base is 9 m?​

Answer 1

Answer:

answer is 424.2857square meters

Step-by-step explanation:

as given right circular cone

so

height=12m

radius=9m

so we can find the slant height by putting Pythagoras theorom

l=√12.12+9.9

=15m

so,

lateral surface area of this cone

πrl

so,

22/7.15.9=424.2875square meters
