Question
**Problem Statement:**

Given the diagram below, if \( G \) is the circumcenter of \( \triangle ABC \), \( DC = 16 \), \( GB = 21 \), and \( AF = 19 \), find each measure. Round answers to the nearest tenth when needed.

**Diagram Explanation:**

The diagram shows a triangle \( \triangle ABC \) with point \( G \) marked as the circumcenter. There are several lines drawn connecting points in the diagram, forming additional segments and points: \( E \), \( F \), and \( D \).

- \( AG \) is a line segment from point \( A \) to point \( G \).
- \( BC \) is a line segment from point \( B \) to point \( C \).
- \( GF \) is a line segment from point \( G \) to point \( F \).
- \( DG \) is a line segment from point \( D \) to point \( G \).

**Given Values:**
- \( DC = 16 \)
- \( GB = 21 \)
- \( AF = 19 \)

**Required Measurements:**

- \( AG = \) 
- \( BC = \) 
- \( GF = \) 
- \( DG = \) 

**Instructions for Solution:**

To solve for each segment measurement, use properties of circumcenters, related geometry, and given values. Ensure answers are rounded to the nearest tenth where necessary.
