Compare the radii of two nuclei with mass number 27 and 64 respectively.

Explanation

To compare the radii of two nuclei with mass numbers 27 and 64, we can use the formula for the radius of a nucleus:

### Step 1: Understand the formula for nuclear radius
The radius \( R \) of a nucleus can be expressed as:
\[ R = R_0 A^{1/3} \]
where \( R_0 \) is a constant and \( A \) is the mass number of the nucleus.
