Question

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

Answer 1

Answer:

solution

height of conical tent =12m

radius =9m

slant height of conical tent =9^2+12^2=81+144=root225=15m

total surface area of cone=

$\pi \: r(r + l) \\ = \frac{22}{7} \times 9(9 + 15) \\ =678.857m ^{2}$

So,678.857m^2 of canvas is required for conical tent.
