Answer:
Area asked for = 900.00 cm 2
Step-by-step explanation:
Surface area of sphere = 4× pi × r ^2
1200 = 4× 3.142 × r ×r
r^2 = 1200 ÷ (4 ×3.142)
= 95.4805856143
Total surface area of hemisphere of the same radius
= surface area of sphere ÷2 + pi r^2
= 1200÷2 + 3.142 × 95.4805856143
= 900.00 cm 2
