Find The Total Surface Area Of This Cone Leave Your Answer In Terms Of Pi 12in 15in class=

Sagot :

Total surface area of a cone is given by,

  • Surface area of the cone = πrl + B

Here, l = Slant height of the cone, r = radius of the circular base and B = Area of the base

   Total surface area of the cone will be 324π in².

From the picture attached,

  • Slant height 'l' = 15 in.
  • Radius of the circular base 'r' = 12 in.

Substitute these values in the formula of the surface area,

Area of the circular base = πr²

                                          = π(12)²

                                          = 144π in²

Total surface area of the cone = π(12)(15) + 144π

                                                   = 180π + 144π

                                                   = 324π in²  

             Therefore, total surface area of the cone is 324π in².
