Answer:
30.17 cm
Step-by-step explanation:
area of  a circular disc=π*r^2
derivative of area=2*π*r
maximum error= derivative * error in radius
i.e . 2*π*r*0.2
 
        
             
        
        
        
AC and DB are the same length. Set the two to equal each other and solve for y.
9y + 1 = 8y +17
Subtract 8y from both sides:
y + 1 = 17
Subtract 1 from each side:
y = 16
Now you know Y you can find the the length of DB:
DB = 8y +17 = 8(16) +17 = 128 + 17 = 145
EB is half of DB:
EB = 145 / 2
EB = 72.5
 
        
             
        
        
        
Answer:
We have, y=f(x)
From graph, when x = 2, y =f(x)=-5. So, functional value at x=2, f(2) = -5
