Find the surface area of the right cone. round your answer to the nearest hundredth. a right cone is drawn. the length of radius of the base is 8 inches and the slant height is 16 inches.

Respuesta :

The surface area of the right cone is 602.88 inch².

What is cone ?

  • The surface traced by a moving straight line (the generatrix) that always passes through a fixed point (the vertex).
  • The path, to be definite, is directed by some closed plane curve (the directrix), along which the line always glides.

Given,

        length of radius of the base is = 8 inches

                          the slant height is  =16 inches.

Now using formula ,

the surface area of right circular cone is a right circular cone = πr(r + l)

So,    r = 8 inches  l = 16 inches

put values in  the formula ,

             surface area of right circular cone = 3.14 × 8 ( 8 + 16 )

                                                                       = 3.14 × 8 × 24

                                                                       = 602.88 inch²

Therefore, the surface area of the right cone is 602.88 inch².
