Formula for surface area of a cylinder:

Plug in values and solve for the radius:

Divide both sides by 

Subtract 90 from both sides

Use the quadratic equation to find the roots
±
(sorry for formatting, Brainly doesn't
allow equations with ± in them)
and 
and 
and 
and 
and 
and
We can't have a negative radius, so that leaves us with r=6 in.
Answer:
Italy - 6am
Taiwan - 1pm
Peru-12am
Turkey-8am
Laos-12pm
Step-by-step explanation:
To use the equation we need a1 and d(the common difference).
We have a1 = 57, we need to find d.
93-84 = 9; 84-75=9; 75-66=9; 66-57=9
d = 9
a350 = 57 + (350-1)(9)
a350 = 57 + (349)(9)
a350 = 57 + 3141
a350 = 3198
i am not sure but it think its 6 root 2
Hello!
if x = -3, just substitute it for x (replace the x with -3)
2(-3) + 6 = 0
2 * -3 = -6
-6 + 6 = 0
I hope this helps, and have a nice day!
