Independent/Dependent Events. Two events are independent if the result of the second event is not affected by the result of the first event. If and are independent events, the probability of both events occurring is the product of the probabilities of the individual events.
 
        
             
        
        
        
Answer:
18.84 meters. 
Step-by-step explanation:
The formula for a circle is πr^2. 
πr^2 = 28.26
3.14 * r^2 = 28.26
r^2 = 9
r = plus or minus 3. 
But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters. 
The formula for the circumference is 2πr. 
2 * 3.14 * 3 = 6 * 3.14 = 18.84. 
So, the circumference of the circle is 18.84 meters. 
Hope this helps!
 
        
             
        
        
        
If it involves an Arc, the inscribed angle is 1/2 of the measure of the are across from it. If the figure inscribed in a quadrilateral, opposite angles are supplementary (when added together equals 180 degrees) This is all I know :)
        
             
        
        
        
Answer:
<h2>r = 3 in</h2>
Step-by-step explanation:
The formula of a volume of a cone:

r - radius
H - height
We have V = 12π in³ and H = 4 in. Substitute:
