The circumcentre of an equilateral triangle is at a distance of 3.2 cm from the base of the triangle. What is the length (in cm) of each of its altitudes?
Answer & explanation
Correct answer: option 1
We know that,
The ratio of the Circumradius and inradius = 2 : 1
and the height = Circumradius + inradius = 2x + 1x = 3x
Circumradius = 3.2 cm
Inradius = 3.2
Then the height = 3.2 × 3 = 9.6 cm
