Answer:
it should be the 3ird one
The arc length is the product of the angle measure in radians and the radius.
... s = r·θ
So, the angle in radians is the ratio of arc length to radius.
... θ = s/r
To convert from radians to degrees, multiply by the conversion factor 180°/(π radians).
... y = s/r·(180°/π)
Then the angle is between
... 15/20·180/π ≈ 42.97
and
... 16/20·180/π ≈ 45.84
Suitable integers in this range are 43, 44, and 45.
One possible integer value of y is 44.
Answer:
π*AB
Step-by-step explanation:
I m not quite sure about your question because it is lack of details.
However, as my per understanding, Meghan decides to walk along arc AB it means she walks an interval equal to the circumference of the circle AB.
So, apply the formula in caculating the circumference of the circle, we have:
π*d = π*AB
So, she walk a π*AB distance.
If you divide both sides by -4 you'll get:
-10x -12
21 is based on your answer that you already have on the sheet
