As tsa of sphere is 4πr^2
So 4πr^2/4πr^2=4/9=r/r=2/3
Now volume of sphere=4/3πr^3
Acc. to Question 4/3πr^3/4/3πr^3=8/27
So ratio is 8:27
So 4πr^2/4πr^2=4/9=r/r=2/3
Now volume of sphere=4/3πr^3
Acc. to Question 4/3πr^3/4/3πr^3=8/27
So ratio is 8:27

4πr^2/4πR^2= r2/R2 =4/9. r/R= 2x/3x
4/3πr3 /(4/3πR3) =
r3/R3 = 8x3/27x3. 8/27
Ratio is 8:27

4/3πr3 /(4/3πR3) =
r3/R3 = 8x3/27x3. 8/27
Ratio is 8:27
