Radius=?
TSA=4 πr²
314=4 ×314/100×r²
314×100/314×4=r²
r=10/2=5cm
Volume=4/3 πr³=4/3 × 314/100 ×5 ×25
== 523.33 cm³

⇒ Here is ur questions answer:
√ We have Given that : Surface area of a sphere = 4πr^2 = 314 sq cm
√ 4x3.14xr^2 = 314 (Where π = 3.14 , 314/100, r is radius)

√ 4x3.14xr^2 = 314 (Where π = 3.14 , 314/100, r is radius)
√ r^2 = (314 x100) ÷( 314x4)
√ r^2 = 25
√ r = 5 cm
√ Radius = 5cm.
√ Volume = ( 4/3) πr^3
= (4/3)x 3.14 x 125
= 523.3333 Square cm ( Approx.........)
