Question

The centre of each circle in the figure lies on the number line. What is the relationship between the circumference of the largest circle and the circumferences of the four smaller circles?​

Answer 1

Circumferences of smaller four and largest circles will be same.

Step-by-step explanation:

Circumference of a circle is represented by

P = 2πr

Radius of the largest circle = 5 units

Circumference of this circle = 2πr

                                              = 2π(5)

                                              = 10π units

Radii of other four smaller circles are $\frac{3}{2},\frac{1}{2},1,2$ units

Individual circumference of these circles = $2\pi (\frac{3}{2}),2\pi (\frac{1}{2}),2\pi,4\pi$ units respectively.

= $3\pi,\pi,2\pi,4\pi$ units

Total circumference = 3π + π + 2π + 4π

                                  = 10π units

Therefore, circumferences of largest and smaller circles will be same.
