Circumradius (Properties of a triangle)
R = abc / 4Δ
Where: Δ = area of triangle, R = circumradius, a = side opposite A, b = side opposite B, c = side opposite C
Solved example
Given: Delta = 7, a = 5, b = 10, c = 4
Find: R (circumradius)
- Formula: R = a·b·c/(4·Δ)
- Substitute the values: R = 10·4·5/(4·7)
- Result: R = 7.142857
Answer: R = 7.142857
