Best ResponseYou've already chosen the best response.0Let r = radius s = slant height h = height \[\large r^2 + h^2 = s^2\] \[\large 6^2 + h^2 = 15^2\] \[\large 36 + h^2 = 225\] \[\large h^2 = 22536\] \[\large h^2 = 189\] \[\large h = \sqrt{189}\] \[\large h = \sqrt{9*21}\] \[\large h = \sqrt{9}*\sqrt{21}\] \[\large h = 3\sqrt{21}\] \[\large h \approx 13.747727\] \[\large h \approx 13.75\]
