This is a combination problem, as the order is not important... So:
There are a total of 6 people, and 4 options available....
n = 6 and r = 4....
Using the combination formula: C(n,r) (Simply use a calculator online or your own)....
C(6,4) = 15.
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:
Circumference:
Radius/circumference ratio:
<h2>Circle D</h2>
Radius:
Circumference:
Radius/circumference ratio:
The radius/circumference ratio for both the circles is , thus making the two circles similar.
Answer:
174 centimeters squared
Step-by-step explanation:
