So @mathmate deleted my comment because "I wasn't explaining my answer" well I did
I clearly stated that you have to make educated guess and I showed how I GOT my answer
so i guess here is my "proper" answer
There is no specific formula for this, so you can make an educated guess
for example:
13*5 = 65 (this isn't right because we need a minimum of 114)
so we continue the guessing
I then next tried
13*9
I got 117,
117 is more than 113
making 9 the minimum amount of rows for the hotel parking lot
there ya go @mathmate is that clear enough?
You find the circumference and multiply it by the central angle. If the central angle is in degrees, you divide that by 360. If the central angle is in radians, you divide by 2pi.
