Given:
The ratio of the volume of the two spheres is 8: 27.
Required:
To find the ratio of their radius.
Step-by-step explanation:
The volume of the sphere is given by the formula:
Where r = radius of the circle.
Let the radius of the spheres are
and volume are
Take the cube root on both sides we get:
The ratio of their radius is 2 : 3.
Final answer:
Thus option a is the correct answer.
