Question

A cone of slant height r and apex O was constructed
1440
O
using a metal lamina in the shape of the sector shown
in the figure. The centre and the radius of the sector
are O and r respectively. n pieces of ice in the shape
of spheres of radius a are placed in this cone. (the
cone is held inverted) If the cone is filled completely
with water when all the ice melts show that
125na3 = 9r3

Answer 1

Fiji I will be a good weekend

Answer 2

Answer:

x/2-1/4 = x/3+1/2

x/2 - x/3 = 1/2+1/4

3x-2x/6 = 1+2/4

x/6 = 3/4

4x = 18

x = 18/4 = 4.5

hope helped !
