Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 + 12) / 4) + 12
C = 3.785 + 12
C = 15.79 meters
Hope this helps! :)
To find the answer, first lets divide the width and length by the scale amount given, 2 cm.
Width: 4 cm / 2 cm = 2
Length: 6 cm / 2 cm = 3
After this, we multiply the result by the amount to scale up, in this case 4 feet.
Width: 2 * 4 = 8 feet
Length: 3 * 4 = 12 feet
Therefore the answer is the first option.

Answer:
lower bound: 315 litres
upper bound: 324 litres
Step-by-step explanation:
The following rules apply:
- if the last digit of the number is 1, 2, 3, or 4; it is rounded down
- if the last digit of the number is 5, 6, 7, 8, or 9.
; it is rounded up
So:
314 is rounded to 310
315 is rounded to 320
324 is rounded to 320
325 is rounded to 330
