Question

find the number of balls each of radius 1cm can be made from a solid sphere of lead of radius 6cm

Answer 1

216 balls can be made by dividing their volume s.

Answer 2

RADIUS OF SMALL BALL = 1cm

VOLUME OF SMALL BALL = 4/3πR³ = 4/3×22/7×1×1×1 = 88/21 = 4.1904276 cm³

RADIUS OF BIG BALL = 6CM

VOLUME OF BIG BALL= 4/3πR³ = 4/3×22/7×6×6×6 = 19008/21 = 905.14286 cm

No of ball can be made of radius 1cm = Volume of big ball/ volume of small ball


PUT. VALUE AND SOLVE U WILL GET THE NUMBER OF SMALL BALL
