Question

calculate the radius of a circle whose circumference is 44cm

Answer 1

Hey...!!!

Circumference = 44 cm
So,
Pi x 2 x radius = Circumference
22/7 x 2 x R = 44
44/7 R = 44
R = 44 x 7/44
R = 7
So, radius = 7 cm

Hope it helps...!!,

Answer 2

Answer:

The radius of the circle is 7cm.

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 = $44$ cm

Let, r be the radius

For calculating radius,

The formula to be used for,

Circumference = $2\pi r$

Substituting the values,

$=> 44= 2\pi r$

$=> r = \frac{44}{2\pi}$

$=> r = 7cm$

Hence, the radius of the circle is 7cm.
