Volume of Sphere=905 1/7
Now, Volume of Sphere=4/3π​r3
(i.e.)905 1/7=4/3*22/7*r3
   =>6336/7=4/3*22/7*r3
   =>19008=4*22*r3
   =>19008=88r3
   
=>r3=216
   =>r=6 cm.

Therefore, Diameter=2r
​=2*6
=12 cm.

TSA=4πr2
=4*22/7*6*6
=452.52 cm2.

Let the radius of sphere = r
now, volume of sphere = 905 1/7cm= 6336/7 cm3
=> 4/3 pi r= 6336/7
=> 4/3 x 22/7 x r= 6336/7
=> r= 6336x3/88 = 216cm 
=> r = 6cm 

therefore, diameter = 2r = 2x6 = 12cm 

now, surface area = 4 x 22/7 x 6 x 6 = 3168/7 cm3

Hopw this answer helps you!!!
