Question

help me please now frends

Answer 1

Given,
FOR CONE
Hieght of the cone=2cm.
Diameter of the base= 4cm.
therefore, radius of base= 2cm.
VOLUME= 1/3*π×r^2×h
=22×2^2×2/(3×7)
=8.38095 cubic cm.
FOR HEMISPHERE
Radius of hemisphere =radius of base of the cone= 2cm.
VOLUME=2/3*π×r^3.
=2×22×2^3/(7×3)
=16.7619 cubic cm.
TOTAL VOLUME OF THE TOY= 8.38095 cubic cm + 16.7619 cubic cm= 25.14285.
