Question

Find the circumference of a circle that has a diameter of 4 m. Use 3.14 for pi.
m

Answer 1

Step-by-step explanation:

The radius of the circle = 4/2 = 2

The circumference of the circle is 2πr

= 2 x 314/100 x 2

= 12.56

Answer 2

Step-by-step explanation:

given that ,

Diameter = 2r = 4m

here "r" is radius.

radius = D / 2 = 4/2 = 2m

Now ,

circumference of circle = 2πr

= 2 × 3.14 × 2

= 12.56

we know that π = 22/7 = 3.14

above we use the value of π = 3.14 given in question.

Hence ,

Circumference of circle = 12.56 m
