A submarine is at a depth of 6500 m below the sea level. It comes up by 400m and then goes down again by 2250 m. If we consider the sea level as zero, what is the current position of the submarine?

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
