Verified answer

Step-by-step explanation:

Volume of hemisphere = 2/3 π r³

Given that, 2/3 × 3.14 × r³ = 1356.48/3

or, r³ = 1356.48/3 × 3/6.28

or, r³ = 1356.48/6.28

or, r³ = 216

or, r = cube root of 216

or, r = 6

Curved surface area of hemisphere = 2 π r²

or, 2 × 3.14 × (6)²

or, 6.28 × 36 = 226.08 cm²
