Circumference of circle = 11.27π ft
so,
C = 2πr
or, 11.27π = 2πr
or, 11.27π/2π = r
so, r = 5.635 ft
now,
diameter = 2r
= 2 x 5.635
= 11.27 ft
        
             
        
        
        
Answer:
2x² +  x - 5
 x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
=  - 2 + 2x² + x - 3 ← collect like terms
 - 2 + 2x² + x - 3 ← collect like terms
= 2x² +  x - 5
 x - 5
