Question

Linda has two porcelain spheres. The radii of the spheres are in a ratio of 2 : 3.

What is the ratio between the volumes of the two spheres?
Answer
8 : 27
8 : 81
16 : 27
16 : 81

Answer 1

radii are measured in linear units, like ft or cm, but volumes are measured in cubic units, like ft^3 or in^3. 2^3=? 3^3=?

Answer 2

2^3 = 6 and 3^3= 9?

Answer 3

My bad, im not asking what is 2*3, that would be 6\[2^3=2\cdot 2\cdot 2\]\[3^3=3\cdot 3\cdot 3\]Thats what i'm looking for.

Answer 4

8 27

Answer 5

thank you

Answer 6
