The questions from today’s “January 31, 2026” on NYT Mini Crossword are a little bit brain teaser. Many people are looking for an answer to it. Here we are sharing answers for clues.
Clue: Halves of diameters
Answer: RADII

Explanation:
In the realm of geometry, the term “radii” is the plural form of “radius.” A radius is a line segment that extends from the center of a circle to any point on its circumference. When you consider the diameter of a circle, it is essentially composed of two radii end to end, stretching across the full width of the circle and passing through its center. Thus, each radius is exactly half of a diameter. This relationship is foundational in understanding the properties of circles and is frequently utilized in various mathematical calculations involving circular shapes. The clue “Halves of diameters” directly points to this fundamental concept, making “radii” the precise answer. This understanding is not only crucial for solving geometry problems but also for practical applications in fields like engineering, design, and architecture, where precise measurements and spatial reasoning are key.
