Step-by-step explanation:
Surface Area of sphere = 616
4 * pie * r2 = 616
4 * ( 22 / 7 ) * r2 = 616
r2 = 49
r = 7 cm
surface area of a hemisphere = 2πr^2
B = 2 x (22/7) x 7 x 7= 44x7 = 308 cm^2

Answer:
→ Curved surface area = 308 cm²
Step-by-step explanation:
→ Surface area = 4πr²
616 = 4πr²
4πr² = 616
2×2× πr² = 616
2πr² = 616÷2
2πr² = 308 ___________(1)
→Curved surface area = 2πr²
Curved surface area = 308 cm²
