Answer:
113.097335529
Step-by-step explanation:
To find the area of a quarter circle, find the area of the whole circle by using the formula area equals pi times r squared. Then divide by 4 and multiply it by 3 to get a three-quarter circle. So we have the area equals pi times 6 squared. The area equals pi times 36. The area equals 113.097335529 (of course you can round it).
