Area of a circle is:
A = (3.14)r^2
The picture shown is that the radius is 4
So,
A = (3.14)4^2
A = 50.2

Let's do the bracket part first,
and solve further as shown,
On the surface of the sea. My best guess because the surface is neither above or below
PEMDAS is order of operations...
Parentheses first, you can combine like terms...
8(6j+7)
Multiplication/division is next...8 times each term inside the parentheses
48j+56
Since there is one term with a variable and one is just a number that is as far as you can go...there are no more like terms...
