Question

Find the circumference

Answer 1

Answer: 20.22 is the circumference of the circle

Explanation:

Given:
Diameter = 6.45
Radius = 6.45/2 =3.22

To find Circumference:
Circumference = 2
`\pi`r

= 2* 3.14 * 3.22

= 6.28*3.22
=20.22

Answer 2

6.45π OR 20.253 units.

Explanation:

Given, Diameter (d) = 6.45 units

=》Circumference = πd = 6.45π

If, π = 3.14, then,

6.45π

= 6.45 * 3.14

= 20.253 units
