can you find the height of the base to the nearest tenth when the surfacearea is 100, the base is 6, and the slant height is 8?

I need one clarification: what shape is this (cone, pyramid, frustum?) and what do you mean by "the base is 6" — base radius, base diameter, base side length, or base area? Also is the given surface area the total surface area or just the lateral area?
Common interpretations and results:
1) If it's a right circular cone and "base is 6" means radius r = 6, with slant height l = 8, then the cone height
h = sqrt(l^2 − r^2) = sqrt(64 − 36) = sqrt(28) ≈ 5.3.
2) If it's a cone and "base is 6" means diameter = 6 (so r = 3), with l = 8, then
h = sqrt(64 − 9) = sqrt(55) ≈ 7.4.
3) If it's a cone with slant height l = 8 and total surface area S = 100 (and the base radius is unknown), solve
πr^2 + π r l = 100 → r^2 + 8r − 100/π = 0.
Solving gives r ≈ 2.9146, then
h = sqrt(8^2 − r^2) ≈ sqrt(64 − 8.497) ≈ 7.4 (to the nearest tenth).
Tell me which interpretation is correct and I will show full steps for that case.
