Question

* A piece of wire is bent into an equilateral triangle of side 6.6 cm. The wire is the best
a circle. What is the radius of the circle?​

Answer 1

Step-by-step explanation:

The length of the wire = 3 * 6.6 = 19.8cm

Circumference of the circle

2\pi r

Therefore,

19.8 = 2 * 22/7 * r

19.8*7/22*2 = r

0.9*7/2 = r

6.3/2 = r

3.15 cm = r
