To determine what 1/4 of pi is, we start with the value of pi, which is approximately 3.14159. When we divide this value by 4, we get:
1/4 of pi = π / 4 ≈ 3.14159 / 4 ≈ 0.7853975
This means that 1/4 of pi is approximately 0.7854 when rounded to four decimal places. This value is often used in various mathematical calculations, particularly in trigonometry and geometry.
