1. **State the problem:** Find the total surface area of a sphere with radius $r=3$ ft. 2. **Formula:** The total surface area $A$ of a sphere is given by $$A = 4\pi r^2$$ where $r$ is the radius. 3. **Substitute the radius:** $$A = 4 \times 3.14 \times 3^2$$ 4. **Calculate the square of the radius:** $$3^2 = 9$$ 5. **Multiply:** $$A = 4 \times 3.14 \times 9 = 4 \times 28.26 = 113.04$$ 6. **Answer:** The total surface area of the sphere is $113.04$ square feet. This means the entire outer surface of the sphere covers $113.04$ ft².
