Question

If the radius of smallest circle in mandala is 10 cm and the radius of the outer circles increases by 1cm, then what will be the diameter of 5th circle ?

Answer 1

Answer:

15cm

10+(5 circles ×1cm)

10+5=15cm

Answer 2

Given:

The radius of smallest circle in mandala = 10 cm

The radius of the outer circles increases by 1 cm

To find :

The diameter of 5th circle

Solution:

The radius of first circle is 10 cm and the radius of outer circle

increases by 1 cm.

So, the radius of fifth circle is, 10 + 1 + 1 + 1 + 1

The radius of 5th circle = 14 cm

Diameter of a circle = 2 × radius of the circle

Diameter of 5th circle = 2 × 14

Diameter of 5th circle = 28 cm

Final answer:

The diameter of 5th circle is 28 cm.
