Question

sphere and cylinder are having same height and same radius. Then how many cylinders can be formed by melting of sphere

Answer 1

take out volume of sphere of that radius and divide by volume of 1cylinder u will get the number of cylinders....

Answer 2

Volume of sphere = volume of the cylinder

4/3 pie r^3 =( pie r^2 h)n

4/3 r = (h) n

4/3r = r/2 ×n

4×2×r = 3r ×n

8r/3r = n

n =8/3

8/3 cylinders can be formed.
