Answer 2

The slant of of a cone (l) is 50 cm.

Step-by-step explanation:

Given,

The radius of a cone (r) = 14 cm and

The curved surface area of a cone = 2200 $cm^2$

Let l be the slant height of a cone.

To find, the slant height of a cone (l) = ?

We know that,

The curved surface area of a cone = $\pi rl$

∴ $\dfrac{22}{7}\times 14\times l=2200$

⇒ $22\times 2\times l=2200$

⇒ $44\times l=2200$

⇒ $l=\dfrac{2200}{44} =50cm$

Thus, the slant of of a cone (l) is 50 cm.
