S =rO
The length of an arc is related to the radius and the central angle in the formula. s = rθ. where s is the arc length, r is the radius and θ is the angle in radians. Remember that to convert from radians to degrees, 2π radians = 360 degrees, so if φ = the angle in degrees, then the equation becomes this:
Answer:

Answer:
The answer to your question is 11 5/8 cups of flour and 6 3/7 cups of sugar
Step-by-step explanation:
Data
The quantities are tripling
The original amount of flour = 3 7/8
The original amount of sugar = 2 1/7
Process
1.- Calculate the amount of flour
-Convert the mix fraction to improper fraction
3 7/8 = (24 + 7)/8 = 31/8
-Multiply by three
31/3 x 3 = 93/8
-Convert to mix fraction

- He needs 11 5/8 cups of flour
2.- Calculate the amount of sugar
-Convert to an improper fraction
2 1/7 = (14 + 1) / 7 = 15/7
-Multiply by three
15/7 x 3 = 45/7
-Convert to mix fraction
