Answer:

Step-by-step explanation:

circumference of a circle = 2πr

9.22 cm = 2*3.14*r

9.22 cm = 6.28*r

9.22 cm /6.28 = r

1.4681 = r

diameter of a circle = 2*r

=2*1.4681

=2.9362

=2.9 cm

Answer:

The Length of diameter of circle is 2.93cm.

Step-by-step explanation:

Given :-

  • Circumference of circle = 9.22 cm

To Find : -

  • Length of diameter, d

Formula Used :-

  • Circumference of circle = π × d
  • where , d is the length of diameter

Solution:-

Using formula

Circumference of circle = π × d

substitute the values

9.22 cm = π × d

Using value of π = 3.14

9.22 cm = 3.14 × d

divide each side by 3.14

9.22 cm / 3.14 = 3.14 × d /3.14

2.93 cm = d

Hence, The Length of diameter of circle is 2.93cm.
