Question

4.9cm is the diameter of the cirle find the circumference of the circle​

Answer 1

Answer:

Step-by-step explanation: Answer : circumference is 15.4 cm

Explanation :-

Given :

Find the circumference of circle whose diameter is 4.9 cm.(Note : take =22/7)

Finding the radius :-

Radius = diameter/2

Given - Diameter = 4.9

=> 4.9/2

=> 2.45 cm

Radius = 2.45 cm

Finding the circumference :-

Circumference of Circle = 2πr

=> 2 x (22/7) x 2.45

=> 15.4 cm

Hence, circumference is 15.4 cm

Answer 2

Answer:

C=15.39cm

Step-by-step explanation:

diameter (d) =4.9 cm

using the formulas

c=2πr

d =2r

solving for c

c= πd=π•4.9=15.3938 cm
