Question

the internal and external diameter of a hollow spherical shell are 6 cm and 10cm respectively .it is melted and recast into a solid cylinder of the height 8 by 3.find the radius of the cylinders.

Answer 1

In both cases volume will remain constant VOL OF SPHERICAL SHELL=VOLUME OF CYLI DER Volume of shell =(4/3). Pie. (R^3-r^3) Volume of cylinder=pie*(r^2)*h (4/3)(22/7)(5^3-3^3)answer=(22/7)(r^2)(8/3) Solve for r and u will get 7 as ur answer
