Answer:
The ferris wheel travelled 434.717 ft.
Step-by-step explanation:
Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:
radius = height/2 = 246/2 = 123 ft
The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:
length = r*(angle in radians) 
length = 123*(9pi/8)
length = 434.717 ft
The ferris wheel travelled 434.717 ft.
 
        
             
        
        
        
Answer:
6,000 children
Step-by-step explanation:
1/3 of 9,000 is 3,000
Meaning that out of 9,000 children, 3,000 WILL get affected. Since we are trying to figure out how many children will NOT get affected, just subtract the number of infected by the total amount which would be 6,000
 
        
             
        
        
        
Answer:
The equation is : r + 2 = 7
Step-by-step explanation:
1+1+1+1+1+1+1 = r + 1 +1
7 = r + 2
R = 7-2
R = 5
 
        
             
        
        
        
Complementary angles add up to 90°
and supplementary angles add up to 180°
Add the two angles together
82+98=180
So the measure of these two angles are supplementary
        
             
        
        
        
Answer:
13
Step-by-step explanation:
g(4) will be found by putting 4 in for r. 
g(4) = 25 - 3(4)
g(4)= 25 - 12 
g(4) = 13
