Question

a piece of wire is bent into an equilateral triangle of side 6.6cm. The wire is then bent into a circle.what is the radius of the circle..​

Answer 1

Answer:

l

Step-by-step explanation:

lenght of triangle boundary = lenght of circumference

formula to find circumference =2π r

so,

2π r=6.6 cm

2×22/7×r=6.6cm

22/7×r=6.6÷2

r=3.3 × 7/22

r=3.3×3.14

r=10.362cm
