The problem here takes a brilliant mind to answer this. This problem can easily be answered using programming because we can not then and there push all the possibilities using paper and pen.

The answer is <span>3816547290. 
</span>
Trying all the possibilities starting form 1000000080 (we are sure that the last number should be 0). Then traversing that number until <span>9999999990. Each traverse, check the number if its divisible to n, so on and so forth.</span>

Why is the answer B? Plz explain.
Ivanshal [37]

Step One

Develop a formula for the perimeter.


Argument

What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.


The "perimeter" [Circumfrence] of a whole circle = 2*pi*r


We are told that whatever you call this the perimeter is 8pi + 16


Step Two

Set up the equation

8pi + 16 = 2*pi*r + 4r Including the line connecting these two.


Step Three

Take out the common factors on the left and right.


8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2

8 = 2r Divide by 2

4 = r


Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.
