Answer:
c = -13.78.
Step-by-step explanation:
21.2x + c  ≡ 5.3(4x - 2.6)
21.2x + c  ≡ 21.2x - 13.78
Equating constant terms:
c = -13.78.
 
        
                    
             
        
        
        
Hi there! 
The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. (two times pi times radius times height) Using this formula, we can plug in the values and solve for the lateral area.
Plugging in the values: LA = 2 x pi x 7 x 9
Simplifying: LA = 2pi x 63
LA = 126pi yd^2
ANSWER:
The 4th option - 126pi yd^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
