Answer 2

Answer:

Circumference = 21.9884cm

Step-by-step explanation:

Given:

Radius of a Circle is 3.5metre

Need to Find:

Circumference of the Circle

Solution:

Circumference of the circle is given by 2πr

Therefore Circumference of a circle whose radius is 3.5metre = 2 x π x 3.5

If value of π = 3.1412....

Circumference = 2 x 3.1412 x 3.5

= 21.9884cm
