For this case we have that by definition, the surface area of a cone is given by:
[tex]SA = \pi * r * S + \pi * r ^ 2[/tex]
Where:
SA: It is the surface area
A: It's the radio
S: It's slant height
Then, replacing the values of the figure in the formula we have:
[tex]SA = \pi * 6 * 15 + \pi * 6 ^ 2\\SA = 90 \pi + 36 \pi\\SA = 126 \pi \ units ^ 2[/tex]
ANswer:
Option A
