Question

three solid metallic spherical balls of radii 3cm 4cm and 5cm are melted into a single ball find its radius​

Answer 1

Answer:

Given r1 =3cm

r2=4cm

r3=5cm

Let the radius of the sphere formed after the melting of 3 spheres be R

Now,

4/3π(r1 cube+ r2 cube + r3 cube)= 4/3 π R cube

(3)3+(4)3+(5)3=R3

27+64+125=R3

R3=216

R=6 cm
