Question

What is the circumference of a circle of diameter 20 cm( π=3.14) ​

Answer 1

Answer:

circumference = 2πr

radius = 20/2 = 10

2 πr

2 × 3.14 × 10

62.8

Answer 2

Answer:

62.8

Step-by-step explanation:

As we know that,

Circumference of a circle =$2\pi r$

Whereas, r is the radius of circle.

Given:-

diameter of circle =20cm

to find radius

20/2=10

so, r=10

Therefore,

Circumference of circle =2×3.14×10=62.8cm
