Question

a hemisphere of radius 8cm is cast into a right circular cone of Base radius 6cm determine the height of the cone, correct to two places of decimal ​

Answer 1

ANSWER:---------------

{ volume of hemisphere = volume of cone}

[2/3×pi×r^3 = 1/3×pi×r^2×h]

[hight = 2×8×8×8/6×6]

multiply. 2×8×8and also divide 8/6(6×6)

[hight = 28.44 cm ]

hope it helps:--

Answer 2

hemisphere

R = 8 cm

Cone

r = 6 cm

height = h

Volume of cone = Volume of hemisphere

πr^2h/3 = 2πR^3/3

r^2h = 2R^3

6X6Xh = 8X8X8X2

h = 1024/36

h= 28.4444444.......

h = 28.44 cm
