Question

an iron block of timings and 28 cm into 14 cm into 11cm
is melted to form three identical solid sphere find the radius of a each
sphere​

Answer 1

Answer:

Step-by-step explanation:the volume of the iron block = (28*14*11)cu.cm

=4312 cu.cm

this volume of iron block is melted to form three identical spheres.

So, the volume of each sphere = (4312/3) cu.cm

Volume of a sphere = (4/3)*(22/7)*(r^3) where r is the radius

or, 4312/3 = (4/3)*(22/7)*(r^3)

or, (4312/3)*(7/22)*(3/4) = r^3

or, 343 = r^3

or, 343^(1/3) = r

therefore, r = 7 .
