Answer:
I believe it is 28.
Step-by-step explanation:
I am not really sure about this answer so please let me know if it is incorrect :)
When you divide the diameter in half, it is 6 (12/2=6). Then you divide it again in half, but you divide it in half from 6 because that is what we were working with just now. Half of 6 is 3 (6/2=3). Now, i'm not sure but we do 3*π*π because we folded the circle two times. 3*3.14=9.42477796077 but you can just say around 9. Then we multiply 9 to π which is 28.2743338823 but again you can just say 28. I hope this helped :D
The area of the resulting shape if a circle with a 12-inch diameter is folded in half and then folded in half again is 9π square inches
The formula for calculating the area of a circle is expressed as shown below:
Area of a circle = πr²
If the circle with a 12-inch diameter is folded in half and then folded in half again the circle will become a quadrant.
The area of the resulting shape will be the area of a quadrant as shown:
Area of a quadrant = πr²/4
diameter = 2r
12 = 2r
r = 6
Area of a quadrant = π(6)²/4
Area of a quadrant = 36π/4
Area of a quadrant = 9π
Hence the area of the resulting shape if a circle with a 12-inch diameter is folded in half and then folded in half again is 9π square inches
