Question : 104 of 200

Marks: +1, -0

The radius of the base of a conical tent is

5 {cm}

. If the tent is

12 {m}

high, then the area of the canvas required in making the tent is ṁ

$300 π {m}^{2}$
$60 π {m}^{2}$
$90 π {m}^{2}$
None of these

Solution:

Here, Radius,

r=5 {m}

and Height,

h=12 {m}

∴

Slant height,

I=√{r^{2}+h^{2}}=√{5^{2}+12^{2}}=13 {m}

∴

Area of canvas required

=π r l

=π × 5 × 13=65 π {m}^{2}
