Step-by-step explanation:

Answer 2

Answer:

The radius of the circle is 0.84cm.

Step-by-step explanation:

In context to the question asked,  

We have to find the radius of the circle,

As per data given in the question,  

We have,

Circumference of circle = $5.28$ cm

Let, r be the radius

For calculating radius,

The formula to be used for,

Circumference = $2\pi r$

Substituting the values,

$=> 5.28 = 2\pi r$

$=> 5.28 = 2 \times \frac{22}{7}\times r$

$=> r = \frac{5.28}{2\times \frac{22}{7} }$

$=> r = 0.84cm$

Hence, the radius of the circle is 0.84cm.
