To solve for the surface area of a sphere, the formula is 4*pi*r^2. Since we are using 3.14 instead of pi, the formula becomes 4*3.14*r^2. To solve, all we have to do is substitute in the radius for r and solve it like a normal question.
SA=4*3.14*r^2
SA=4*3.14*6^2
SA=452.16
Since we used 3.14 instead of pi, we have to say this is an approximate answer. This means the surface area of this sphere is 452.16 square inches.
