Question

if a right circular cone has a later surface area of 175 Pi centimetre square and its plant and its slant height is 25 cm find its height of the cone

Answer 1

lateral surface area of a right circular cone is pi x r x l
pi x r x l = 175pi
r x 25 = 175
r = 7
square of slant height = square of radius + square of height
square of 25 = square of 7 + square of height
625 = 49 + square of height
square of height = 625 - 49
                           = 576
height = root 576
height = 24
