What is the approximate circumference of the circle shown below

The correct option is i.e, .

Further explanation:

A circle is the set of all points on a plane whose distance from a fixed point is constant.

There are infinite points on the circle and distance of these points from the center of circle is always constant.

The distance from the center of the circle to any point on the circle is called as radius of the circle.

The circumference is the length of the circle and the formula of the circumference for the circle is as follows:

 …… (1)

Here, is the radius of the circle and the value of is approximately equal to .

The formula of the circumference for circle is terms of diameter is as follows:

Here, is the diameter of the circle.

The relationship between diameter and the radius is as follows:

.

From attached Figure 1 it is observed that the radius of the circle is .

Substitute in the equation (1) to obtain the value of circumference as follows:

Therefore, the circumference of the circle is .

Thus, the correct option is .

Keywords:  Circle, radius of a circle, point, distance, diameter, circumference, d=2r, C=2pir, 129. centimeter, locus of circle, approximate, value, shown below.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
