The lateral area of a cone is 555 pi cm^2. the radius is 15.1 cm. what is the slang height to the nearest tenth of a centimeter? a- 36.8 cm b- 11.7 cm c- 83.8 cm

The lateral area of a cone is given by
  A = πrh
where r and h represent the radius and slant height, respectively. Substituting given values, you have
  555π cm² = π(15.1 cm)h
  h = (555/15.1) cm ≈ 36.8 cm

The appropriate selection is
  A- 36.8 cm
