1. The problem asks to find the area of a circle with diameter 8 ft, using \(\pi = 3.14\) and no rounding. 2. The formula for the area of a circle is: $$\text{Area} = \pi r^2$$ where \(r\) is the radius of the circle. 3. The radius \(r\) is half the diameter, so: $$r = \frac{8}{2} = 4 \text{ ft}$$ 4. Substitute \(r = 4\) and \(\pi = 3.14\) into the area formula: $$\text{Area} = 3.14 \times 4^2$$ 5. Calculate the square of the radius: $$4^2 = 16$$ 6. Multiply by \(\pi\): $$\text{Area} = 3.14 \times 16$$ 7. Perform the multiplication: $$\text{Area} = 50.24 \text{ ft}^2$$ 8. The area of the circle is \(50.24\) square feet. Final answer: \(50.24 \text{ ft}^2\)
8 ft
