Answer:
The degree of 9 is 0
Step-by-step explanation:
Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.
As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.
in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.
The diameter will be 8 feet because the measurement is after completing a complete circle. Radius will be 4 feet since diameter is twice radius.
We need to find the area of circle using the formula (πr²)

When 2 tangents are joined to a circle, the tangents are of equal length so the triangle is isosceles. Then again it is possible for it to be equilateral.
