The vertical distance between Dean and Jeff is 13 ft below the surface
Explanation:
Jeff dove 39 ft below the surface and then ascends 18 ft
-39 - 18 = 21
Jeff is 21 ft below the surface

Dean is 34 ft below the surface
-34 - (-21) = -13 ft
-----------------
So, Dean and Jeff are 13 feet away from each other (vertical distance).

Answer:
530.998cm^2
Step-by-step explanation:
General formula for the area of a circle is πr^2
And π is given to be 3.142
R is 13 cm
So let's apply the formula
Area=3.142×(13^2)
Area=3.142×169
Area=530.998cm^2
So the area of the circle is 530.998cm^2
