We are given a square with a side length of 74, and a circle inscribed in the square. We are asked to find the probability that a randomly chosen point within the square lies inside the circle. The key to solving this problem is understanding the ratio of the areas of the circle and the square.

### Step-by-step solution:

1. **Area of the square:**
   The area of a square is given by:
   \[
   \text{Area of the square} = \text{side length}^2 = 74^2 = 5476
   \]

2. **Radius of the inscribed circle:**
   Since the circle is inscribed in the square, the diameter of the circle is equal to the side length of the square. Therefore, the radius of the circle is half the side length of the square:
   \[
   \text{Radius of the circle} = \frac{74}{2} = 37
   \]

3. **Area of the circle:**
   The area of a circle is given by:
   \[
   \text{Area of the circle} = \pi r^2 = \pi (37)^2 = \pi \times 1369
   \]
   \[
   \text{Area of the circle} \approx 3.1416 \times 1369 = 4300.84
   \]

4. **Probability calculation:**
   The probability that a randomly chosen point is inside the circle is the ratio of the area of the circle to the area of the square:
   \[
   \text{Probability} = \frac{\text{Area of the circle}}{\text{Area of the square}} = \frac{4300.84}{5476}
   \]
   \[
   \text{Probability} \approx 0.7852
   \]
   Converting this to a percentage:
   \[
   \text{Probability} \approx 0.7852 \times 100 = 78.52\%
   \]

### Final answer:
The probability that a randomly chosen point is inside the circle is approximately **78.5%** (rounded to the nearest tenth of a percent).
