Question

if the circumference is 176 CM. what will be the circle?
​

Answer 1

Answer:

The answer is 28 CM

Step-by-step explanation:

Given : We have given that the circumference is 176 CM

To FInd: What will be the circle

Solution:

the radius of a circle is r

We assume AB = r

The Circumference of a circle is equal to 2πr

So, equating the 2πrto 176 cm,

we get  2πr=176 cm

Now, substitute the value π=227, we get  2×227×r=176

Now, we get ,447×r=176

Now, cross multiply to get the value of r

⇒r=176×744

Now, we multiply 176 with 7 and divide the number obtained with 44, we get

⇒r=123244

⇒r=28 cm

So, the radius of the circle is 28 cm.
