Answer 2

Answer:

H = (c) 900cm

Step-by-step explanation:

Volume of Sphere = 4$\pi$$r^{2}$

                               = 4 x 22/7 x $(6/2)^{2}$

                               =4 x 22/7 x 9

Volume of Wire = $\pi$$r^{2}$H

                          = 22/7 x $0.2^{2}$ x H

                          = 22/7 x 0.04 x H

Volume of Sphere = Volume of Wire

22/7 x 0.04 x H = 4 x 22/7 x 9

4/100 x H = 4 x 9

.: H = 900cm
