Question

The Base radius of a cone is 5cm. and its height is 12cm. Find its slant height .
​

Answer 1

Answer:

r=5

h=12

l=?

l=√h^2+r^2. (formula)

√144+25

√169

so slant height is 13cm

Answer 2

Given :-

• The Base radius of a cone is 5cm.

• The height of cone is 12cm.

To Find :-

• The slant height of cone .

Solution :-

We know, the slant height of cone is l

l² = h² + r²

Where,

The Base radius of a cone is r = 5cm.

The height of cone is h = 12cm

l² = h² + r²

➝ l² = (12)² + (5)²

➝ l² = 144 + 25

➝ l² = 169

➝ l = √169

➝ l = 13 cm

The slant height of cone is 13 cm.
