Question

If the total surface area of a cone of radius 7cm is 704cm^2,then find it's slant height
ول​

Answer 1

Answer:

The radii if the cone is 7 cm. The total surface area of the cone is 704 sq cm. => L = 25 cm. So the slant height of the cone is 25 cm.

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Total surface area of cone=πr² +πrl (r=Radius, l=slant height)

⇒704= πr(l+r)

⇒704= 22/7 ×7(l+7)

⇒ 704/22 - 7 = l

⇒l=25 cm.
