Question

Please find the surface area of the cone (image attached) and reduce answer to nearest tenth, if necessary.

Answer 1

`S.A = 135.6 yd^2` (

Explanation:

Surface area of cone is given as:

Surface Area (S.A) = πr(r + l)

Where,

`r = radius = 3 yd`

`l = slant height = 11.4 yd`

Take π as 3.14

Plug the given values into the formula to find the surface area.

`S.A = 3.14*3(3 + 11.4)`

`S.A = 9.42(14.4)`

`S.A = 135.6 yd^2` (rounded to the nearest tenth)
