Question

A metelic cylinder of diameter 5cm & height 3 ½cm is melted am casted into a sphere find the radius

Answer 1

Answer:

r = 2.54

Step-by-step explanation:

Vol. of cylinder = Vol. of sphere

PI × r^2 × h = 4/3 × PI × r^3

:. 22/7 × 2.5 × 2.5 × 3.5 = 4/3 × 22/7 × r^3

:. r^3 = 16.40625

:. r = 2.54
