Two sphere of radius 2 cm each are melted and casted into a single sphere. What would be the radius of this new sphere?

Two sphere of radius 2 cm each are melted and casted into a single sphere. What would be the radius of this new sphere? Correct Answer 161/3 cm

Given, r = 2 cm, let the radius of new sphere = R According to the question 2 * ((4 / 3) * πr3) = (4 / 3) * πR3 2 * ((4 / 3) * π (2)3) = (4 / 3) * πR3 2 * 8 = R3 R = 161/3 cm
