If the side of an equilateral triangle is 6
3
cm, then what is the length (in cm) of the circumradius of that triangle?
- A4
- B6
- C8
- D12
Solution & Step-by-step Explanation
The formula for the circumradius (R) of an equilateral triangle with side a is:
R=
3
a
Given that side a=6
3
cm:
R=
3
6
3
=6cm
Therefore, the length of the circumradius is 6cm.
R=
3
a
Given that side a=6
3
cm:
R=
3
6
3
=6cm
Therefore, the length of the circumradius is 6cm.
