Answer:
A
Step-by-step explanation:
-1.78 is more than -2 but less than -1.5.
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.
You are measuring the distance between two points on a grid. To do this you are basically using Pythagorean theorem (A^2 + B^2 = C^2) and then square rooting it in the end. It’s all the steps in one formula
