Question

fnd the diameter of a circle whose circumference is 66m​

Answer 1

Step-by-step explanation:

Circumference of a circle is 2πr.

so, 2πr = 66

= r = 33/π

= r = 33×7/22

hence , diameter = 21/2 × 2

= 21cm.

Answer 2

Answer:

The Diameter of the circle = 21m

Step-by-step explanation:

The formula to find the circumference of any circle:

Circumference of circle = 2πr or πd 

Here, r is the radius and d is the diameter of circle.

The information given to us:

Circumference of the circle = 66 m

Now solving:

=> 2πr = πd = 66 

=> 22/7 × d = 66

=> 22 d =  66×7 

=>  d = 66×7  / 22

=> d = 3×7 = 21

Therefore,the Diameter of the circle = 21m
