Question

what is the value of R if the solid glass of radii r cm 6cm and 8cm and melted into solid sphere of radius 9 CM​

Answer 1

Answer:1 cm

Step-by-step explanation:

sum of the volumes of smaller spheres = volume of larger sphere

4/3π(r^3+6^3+8^3) = 4/3πR^3

(r^3+216+512) = 729

r^3 = 729-728

r = 1 cm....
