Lateral Cone Area = PI * radius * slant height

slant height ^ 2 = 6^2 + 10^2

slant height ^ 2 = 36 + 100

slant height ^ 2 = 136

slant height ^ 2 = 11.6619037897

Lateral Cone Area = PI * 6 * 11.66

Lateral Cone Area = 219.6744

That's my calculation and I used an online calculator which says the same thing. It is NOT one of the choices.
