All circles are similar shapes.
However, we can prove that these circles are similar by finding their radius-circumference ratios.
<h2>Circle B</h2>Radius:
- 4 units
Circumference:
Radius/circumference ratio:
Radius:
- 2 units
Circumference:
Radius/circumference ratio:
The radius/circumference ratio for both the circles is , thus making the two circles similar.
