If volumes of two spheres are in the ratio 64:27 then the ratio of their surface areas is

Explanation

To find the ratio of the surface areas of two spheres given that their volumes are in the ratio of 64:27, we can follow these steps:

### Step 1: Understand the relationship between volume and radius
The volume \( V \) of a sphere is given by the formula:
\[ V = \frac{4}{3} \pi r^3 \]
where \( r \) is the radius of the sphere.
