Metallic spheres
Answer :
Given,
The radius (r1) of 1st sphere = 6 cm
Radius of 2nd sphere (r2) = 8 cm and
Radius f third sphere (r3) = 10 cm
Let the radius of the resulting sphere be R;
So now we have,
Volume of resulting sphere = Volume of three metallic spheres
⇒ πR3 =
⇒πR3 =
⇒ R3 = 216 + 512 + 1000
⇒ R3 = 1728
⇒R =
R = 12 cm
So, the radius of the resulting sphere is 12cm.
