Question

the circumference of the circle is 62.8 cm. find the radius of the circle {take pi =3.4 }​

Answer 1

Answer:

Radius = R

Circumference = C = 62.8

Pie = 3.4

$C = 2\pi R = 2 X 3.4 X R\\62.8 = 6.8 R\\\\R = 9.23 UNITS$

C = 2 X pie X R

Answer 2

The given data in the question are as below

The circumference of the circle is $62.8$ cm.

Value of $\pi$ =$3.4$

We have to find the radius of the circle

As we know that ,

Circumference of the circle =$2\pi r$

Where , r = radius of circle

So, $62.8$=$2\times 3.4\times r$

Dividing $62.8$ by $2$ and $3.4$ it will get

          r = $\frac{62.8}{2\times 3.4}$

By multiplying $2$ by $3.4$ we get,

          r=$\frac{62.8}{6.8}$

Dividing $62.8$ by $6.8$   we get,

          r=$9.2352$ cm

Therefore, Radius of the circle is equal to $9.2352$ cm.
