Plug in the values into the base equation; 

l=2 \pi r(  \frac{ \alpha }{360} ) <-- alpha is the degree 

l=2 \pi (12)(9/360) 
l=1.88495 ft ≈ 1.90 ft 

Hope I helped :)

Jenny is throwing a surprise birthday party for her best friend Katie. She has decided to make Katie’s favorite dish, meat loaf.
miskamm [114]

Answer:

The answer is below

Step-by-step explanation:

a) The recipe for the meat loaf used by Jenny can serve a total of 8 people. Since there are 40 people in total to serve, the number of each ingredient needed is:

Number of each ingredient = total number of people / number of people served by one recipe

Number of each ingredient = 40 / 8 = 5

b) Since each recipe contains 1 1/2 lb (1.5 lbs) of ground beef, the total amount of ground beef needed to feed everyone is:

Total amount of ground beef = 1.5 lbs * 5 = 7.5 lbs

c) Since one serving would require 8 oz of milk. To serve everyone, the amount of milk needed is:

Amount of milk = 40 people * 8 oz = 320 oz

128 oz = 1 gallon

Amount of milk = 320 oz * 1 gallon / 128 oz = 2.5 gallon
