Hope this will help you out

Answer 2

718.66 cm³

Step-by-step explanation:

Total Surface Area of a hemisphere= 462cm²

=> 3πr² = 462

=> 3 x 22/7 x r² = 462

=> 66/7r² = 462

=> r² = 462 x 7/66

=> r² = 7 x 7

=> r = √49

=> r = 7

Volume of a hemisphere = 2/3πr³

= 2/3 x 22/7 x 343

= 44/3 x 49

= 2156/3

= 718.66 cm³
