Question

a metallic sphere of radius 9 cm is melted to form a cylinder of radius 6 cm find the height of the cylinder​

Answer 1

Answer:

26.9

Step-by-step explanation:

Radius of sphere = 9cm

volume of sphere = 4/3πr³

=4/3×22/7×9×9×9

= 3054.85cm³

Radius of cylinder = 6cm

volume of cylinder = volume of sphere

πr²h = 3054.85

π × 6×6 × h = 3954.85

πh = 3954.85/36

πh = 84.85

h = 84.85 × 7/22

h = 26.9cm
