The slant height is 11 and the radius is 6 Could you help me find the surface area ?
I believe i used Pythagorean theorem correctly but ig not

102π    or   320.44

Step-by-step explanation:

Surface area = πr² + πr*slant height   (no Pythagorean theorem here)

                     = π*6² + π*6*11

                     = 102π    or   320.44

320.44 unit^2 to the nearest hundredth.

Step-by-step explanation:

Cone with slant 11 and  radius 6.

The total surface area = πr(r + L)

= 6π * (11+6)

= 320.44245

sorry, i don't know i just need points, i'm new here. chao
