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).

Answer:
The student answer is wrong. The correct length of the hypotenuse is 12
Step-by-step explanation:
The question is incomplete without diagram. Find the diagram attached below.
The longest side of the right angled triangle is the hypotenuse.
The side facing the angle 30° is the opposite side of the triangle.
To find the hypotenuse, we will use the SOH CAH TOA method in trigonometry identity.
According to SOH:
Sin30° = Opposite/Hypoenuse
Sin30° = 6/Hypotenuse
Hypotenuse = 6/sin30°
Hypotenuse = 6/0.5
Hypotenuse = 6×2
Hypotenuse = 12
The student answer is wrong. The correct length of the hypotenuse is 12
