Answer 2

Answer

To find the ratio between their surface areas

We must know the ratios between their radius and the ratio if volume is 8and27

So we know in the volume formula of sphere r is in cubic form

When we will take out its root ao the ratio between their radius will be 2and3

Now the surface areas formula is 4 pie r×r

And 4 pie will cut r×r too

At last we will do the square of 2 and 3

And the ratios will be 4:9.
