Answer:
3.14 ft
Step-by-step explanation:
Your formula is A=πr². If you expand it, the formula is π × r². (r = radius)
Your radius is given, which is 1 ft.
If you use the formula, the equation ends up being π×1²
1² is 1, because 1 to the power of anything equals 1.
π ≈ 3.14. Meaning that 1 × 3.14 = 3.14, making the area 3.14ft.
