In an equilateral triangle inradius is 4 cm. what is the circumradius ? |
6 cm 8 cm 12 cm 2 cm |
8 cm |
Formula used Inradius of equilateral triangle = \(\frac{a}{2√3}\) Circumradius = \(\frac{a}{√3}\) Calculation Inradius = \(\frac{a}{2√3}\) = 4 = a = 8√3 Circumradius = \(\frac{a}{√3}\) = \(\frac{8√3}{√3}\) = 8. Therefore, answer is 8. |
