Question

3 sphere of 6cm, 8cm and 10cm radii are melted to recast to form a cone of 16 cm radius . find the height of tge cone.​

Answer 1

Step-by-step explanation:

here's your answer....

Answer 2

Volume of sphere = 4/3πr³

volume of first sphere = 4/3 ×22/7 ×

6×6×6=905.14cm³

volume of second sphere = 4/3× 22/7×8×8×8

= 2145.52cm³

Volume of third sphere = 4/3 ×22/7×10×10×10

= 4190.47cm³

Volume of new cone = 905.14+ 2145.52+ 4190.47

= 7241.13cm³

πr²h= 7241.13

π×16×16×h = 7241.13

πh = 7241.13/16 ×16

πh = 7241.13

h = 7241.13 ×7/22

h= 2303.9cm

h = 23.03m
