Question

a cylindrical metal rod of 3 CM length of 20 CM diameter is melted to make spheres of 1 cm radius how much the spheres are get and volume of sphere

Answer 1

hey buddy.....check your answer.....

Answer 2

.volume of cylindrical metal rod = X × volume of 1cm radius spheres.

π r^ 2 h = X × 4÷3πr^3

π×10×10×3. = 4÷3×1×π×X

300 = 4÷3×X

900 = 4X

225= X

so no: of spheres = 225 spheres.

volume of sphere = 4.190 cm^ 3.
