Answer:
3.14 ft² or 2,917 cm²
Step-by-step explanation:
To do this, we need to know the expression to calculate the area of a circle.
The area of any circle is:
A = πr²
Where:
π: value of pi, which is 3.14
r: radius of the circle, in this case 1 ft
Calculating the area in units of ft:
A = 3.14 * (1)²
A = 3.14 ft²
Now, if you convert the foot to cm we have:
1 * 30.48 = 30.48 cm
Solvinf for A:
A = 3.14 * (30.48)²
A = 2,917.15 cm²
