Given an equilateral triangle with side (a) equal to 10
Calculate the other relevant items in this triangle
Calculate Perimeter:
P = 3a
P = 3 x 10
P = 30
Calculate Semiperimeter s:
| s = | P |
| 2 |
| s = | 30 |
| 2 |
s = 15
Calculate Area (A):
| A = | a2√3 |
| 4 |
| A = | 102√3 |
| 4 |
| A = | 100√3 |
| 4 |
| A = | 173.20508075689 |
| 4 |
A = 43.301270189222
Calculate Bisector
| ha-ma-ta = | a√3 |
| 2 |
| ha-ma-ta = | 17.320508075689 |
| 2 |
ha-ma-ta = 8.6602540378444
Calc. Circumscribed Circle Radius
| R = | a√3 |
| 3 |
| R = | 17.320508075689 |
| 3 |
R = 5.7735026918963
Calculate Inscribed Circle Radius
| r = | a√3 |
| 6 |
| r = | 17.320508075689 |
| 6 |
r = 2.8867513459481
P = 30
s = 15
A = 10
s = 15
A = 10
What is the Answer?
P = 30
s = 15
A = 10
s = 15
A = 10
