Answer:
8.2 cm
Explanation:
mass of one sphere = m
mass of other sphere = 8 m
Radius of first sphere = r = 4.10 cm
let the radius of another sphere is R
As we know that mass = volume x density
Let the density of the rock is d.
density of rock remains same.
density of small sphere = density of big sphere
mass of small sphere / volume of small sphere =
mass of big sphere / volume of big sphere
R = 2 r
R = 2 x 4.10 = 8.2 cm
Thus, the radius of big sphere is 8.20 cm.
