Equilateral Triangle side = 11
Enter Side (a)
Given an equilateral triangle with side (a) equal to 11
Calculate the other relevant items in this triangle
Calculate Perimeter:
P = 3a
P = 3 x 11
P = 33
Calculate Semiperimeter s:
| s = | P |
| 2 |
| s = | 33 |
| 2 |
s = 16.5
Calculate Area (A):
| A = | a2√3 |
| 4 |
| A = | 112√3 |
| 4 |
| A = | 121√3 |
| 4 |
| A = | 209.57814771583 |
| 4 |
A = 52.394536928959
Calculate Bisector
| ha-ma-ta = | a√3 |
| 2 |
| ha-ma-ta = | 19.052558883258 |
| 2 |
ha-ma-ta = 9.5262794416288
Calc. Circumscribed Circle Radius
| R = | a√3 |
| 3 |
| R = | 19.052558883258 |
| 3 |
R = 6.3508529610859
Calculate Inscribed Circle Radius
| r = | a√3 |
| 6 |
| r = | 19.052558883258 |
| 6 |
r = 3.1754264805429
