Question

The circumference of a circle is 35.2m.find radius

Answer 1

Answer:

2πr=circumference

2πr=35.2

2*22/7*r=35.2

r=35.2*7/44

r=5.6m

Answer 2

Answer:

Radius of circle is 5.61 m.

Step-by-step explanation:

Given -

Circumference of circle is 35.2 m

To find -

The radius of circle

Solution -

The circumference means the length of the complete arc of a circle.

As we know that,

Circumference of circle = $2 \times \pi \times r$

Where,

r is a radius of circle.

Put the given values in these formula we get

$35.2 = 2\pi \times r$

$\frac{35.2}{2\pi} = r$

$\frac{17.6}{\pi} = r$

The value of π is 3.14 .

$\frac{17.6}{3.14} = r$

$r = 5.61$

So,

Radius of circle is 5.61 m.
