Answer:
x² + y² = 42.25
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
here r = 6.5, hence
x² + y² = 6.5², that is
x² + y² = 42.25 ← equation of circle
The geometry is that the number of sides for a 15- gon is 15 sides and the angles are 156° each.
<h3>How to calculate the angle?</h3>
The total angles in a 15 gon will be calculated as:
= (n - 2) × 180
= (15 - 2) × 180
= 2340
The value of each angle will be:
= 2340/15
= 156°
The total angles in a 16 gon will be calculated as:
= (n - 2) × 180
= (16 - 2) × 180
= 2520
The value of each angle will be:
= 2520/16
= 157.5°
