Question

A cylinder radius 12 cm and height 10 cm is melted and recasted into sphere of radius 6 cm.how much sphere got?

Answer 1

Answer:

VOLUME OF CYLINDER = VOLUME OF SPHERE

==> πR²h = 4/3πr³

==> π×(12)²×10 = 4/3π(6)³

==> 144×10×π = 4/3×216 π

==> 1440 π = 4 × 72 π

==> 1440 π = 288 π

==> 1440π / 288π = no. of sphere

==> 5  = TOTAL NUMBER OF SPHERE

answer = 5
