-20 because 40 is a positive and spent is negative
For a 7 sides polygon which is called heptagon or septagon
Interior angles = (7-2)*180/7 = 128.57°
Exterior angle = 180 - 128.57 = 51.43°
Central angle = 360/7 = 51.43°
The statements which are correct:
<span>3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle
</span>
<span>5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57°
</span>
<span>7. The central angle ABCDEFG is the same measure of the exterior angle
</span>
Answer:
D!
Step-by-step explanation:
Answer:
You can calculate the area of the circle
We know the formula is: 
And if diammeter is 800, then the radio is a half: 400
We replace:
feet
So now we can divide:
502654/1000 = 502,654 minutes
