Answer:
11 inches
Step-by-step explanation:
you can cross multiply
 inches cents
 16 80
 x 55
16×55 = 80x
80x= 880
x= 880/80
×= 11 inches
 
        
                    
             
        
        
        
Answer:
There are 6 sandwich choices.
Step-by-step explanation:
2*3=6
 
        
             
        
        
        
Arc length = rθ    [r = radius of the circle, θ = central angle in radians]  ⇒
2π = 8*θ   ⇒   θ = 2π/8 = π/4
        
                    
             
        
        
        
Though you do not provide a diagram, I am going to give this a try by assuming that O is the center of the circle, OA is a radius, and angle AOB is a central angle that measures 88 degrees.
We want to find out the area of sector AOB. First, we need to find the area of the entire circle. The area of a circle is given by 

 and since the radius of this circle is equal to 1, the area is 

Next we need to know what fraction of the circle sector AOB represents. The distance around the circle is 360 degrees but the central angle that intercepts arc AB is 88 degrees. That meas that the fraction of the circle the sector represents is given by 

We multiply this by the area to obtain 

 which is the area of the sector.
