Question

if the circumference of a circle is 176 cm, find its radius​

Answer 1

Answer: it's radius is 28 cm

Step-by-step explanation:

Let, circle's radius = r cm

the circumference of a circle is 176 cm

Then according to the question,

2πr = 176

, 2×(22/7)×r = 176

, r = 28 cm

Answer 2

Answer:

Radius of circle is $28\ cm$ .

Step-by-step explanation:

To find : radius of circle .

Given : circumference of a circle is 176 cm .

Solution :

• As per given that we know that circumference of a circle is 176 cm  . We are asked to find radius of circle.
• We use following formula to find circumference of circle, using this formula we find radius of circle by substituting the given values.

       Circumference of circle $= 2\pi r$

                                        $176 = 2\times \frac{22}{7}\times r \\\\r = \frac{176\times 7 }{2\times 22} \\\\r = 4\times 7 \\\\r = 28\ cm$
