Answer:
3054 6/7 cm³
Step-by-step explanation:
The surface area of a sphere is 1018 2/7 = 7128/7 sq.cm
The surface area of a sphere is = 4πR²
=> 4πR² = 7128/7
Using π = 22/7
=> 4 (22/7) R² = 7128/7
=> 4 (22) R² = 7128
=> R² = 81
=> R = 9 cm
Volume of a sphere = (4/3)πR³
= (4/3)(22/7)9³
= 21384/7 cm³
= 3054 6/7 cm³
