Question

What is the circumference of the circle with a radius of 4.5 meters? Approximate using π = 3.14.

14.13 meters
28.26 meters
56.52 meters
63.59 meters

Answer 1

Answer: the circumference of this circle is : 28.26 meters.

Explanation:

The formula for circumference is = 2*pi*radius

Here,

pi=3.14

radius=4.5meters

hence,

using the formula; 2*pi*r

circumference =2 * 3.14 * 4.5m

circumference = 28.26 meters.

Answer 2

The Circumference of circle os 28.26 meters.

Step-by-step explanation:

Given : Radius of circle is 4.5 meter

To Find : Circumference of circle

Using Formula :

`\leadsto\sf{Circumference_((Circle)) = 2 \pi r}`

Solution :

Finding the Circumference of circle by substituting all the given values in the formula :

`\leadsto\sf{Circumference_((Circle)) = 2 \pi r}`

`\leadsto\sf{Circumference_((Circle)) = 2 * \pi * r}`

`\sf{\leadsto{Circumference_((Circle)) = 2 * 3.14* 4.5}}`

`\sf{\leadsto{Circumference_((Circle)) = 6.28* 4.5}}`

`\sf{\leadsto{Circumference_((Circle)) = 28.28 \: meteres}}`

Hence, the Circumference of circle is 28.26 meters.
