Step-by-step explanation:
360 degrees in a circle
32/360 of total area is sector area
area=pir^2
r=8.5
area=pi8.5^2
area=226.980022 mm^2
multiply it by 32/360
sector=20.17600195555556
round
sector=20.2
C is answer
Answer:
Your answers would be:
x = 10 and x = -8
Step-by-step explanation:
Solve for the zeros:
x² - 2x - 78 = 2
Subtract both sides by 2.
x² - 2x - 80 = 0
Use the quadratic formula: 
a = 1
b = -2
c = -80
Plug in and solve:

Answer:
The whole cookie weighs more.
Step-by-step explanation:
Parts make up the whole? At first i would think that the weight
would be the same; however unless there is a 'perfect' cookie out
there, air does get trapped in the whole cookie, which is expunged
from the whole cookie when broken apart. Macro level = the same,
micro level = the cookie as a whole weighs more.
