The ratio of the base area of a hollow cone to that of its curved surface is 1:4. If its base radius is 7cm, calculate the slant height of the cone
Increase 135 in the ratio 3:5
Given that x2 + y2 + k = 60 and x = \(\sqrt{10}\) when y = 4, find the value of k.
Simplify the expression: \(Log_{4}16\) + \(Log_{3}27\) + \(Log_{8}4096\)
