Question

find the radius of a circle whose circumference is 176 CM ​

Answer 1

Answer:

circumference of the circle = 2πr

176cm = 2× 22/7 × r

176 cm = 44/7 × r

176cm ÷ 44/7 = r

176cm× 7/44 = r

4 × 7cm = r

28cm

Answer 2

Answer:

The radius of the circle is 28cm.

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 = $176$ cm

Let, r be the radius

For calculating radius,

The formula to be used for,

Circumference = $2\pi r$

Substituting the values,

$=> 176= 2\pi r$

$=> 176= 2 \times \frac{22}{7}\times r$

$=> r = 176\times \frac{7}{22} \times \frac{1}{2}$

$=> r = \frac{1232}{44}$

$=> r = 28cm$

Hence, the radius of the circle is 28cm.
