Same as all the other ones like this.
Since the two figures are similar . . .
-- The ratio of of their volumes is R³ .
-- The ratio of their surface areas is R² .
-- The ratio of their dimensions is R .
So R³ is 729 / 2744 .
Take the cube root of that and you'll have R .
Then square R and you'll have the ratio of their surface areas.
Because 1/2 of 6 =1/3 and 1/2×1/3=1/6
Answer: 9 is true, 10 is false
Step-by-step explanation:
The key to these problems is to make sure the sequence of the letters is equal: 10 would be correct if they said DF ≅XZ
If 
, then by rationalizing the denominator we can rewrite
Now,
