Answer:
The balanced chemical equation is ;
Step-by-step explanation:
When barium hydroxide react with water it gives an alkaline solution of barium hydroxide.
The balanced chemical equation is given as:
according to stoichiometry,when 1 mole of barium oxide reacts with 1 mole of water it gives 1 mole of barium hydroxide.

c = 2πr Divide each side by 2π
r = C/2π Insert values
r = 48/(2×3.14)
r = 48/6.28
r = 7.6 in
