-|-10|-(-10) 
A negative outside of the “ | “ means that one number inside will be negative . -10-(-10)
An imaginary | will “appear” in between the two negative signs or it will turn into an addition sign. 
-10+10 
A positive subtracts negatives from the negative number. The answer is 0 
I hope this helped.

Answer:
   (c)  31°
Step-by-step explanation:
Angles 1 and 2 are congruent. Each is half the sum of the subtended arcs:
   ∠1 = ∠2 = (37° +25°)/2 = 31°
 
        
                    
             
        
        
        
Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
