B i think that because there’s no quantity
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

Answer:
Intercept - 1
Slope - 3
Step-by-step explanation:
in y=mx+b
m is the slope and b is the y intercept
So
a. so 100-1/10 of 100 or 100-10=90
then second dose minus 10% or 90-9=81
third dose 81 minus 10%=81-8.1=72.9
fourth dose 72.9 minus 10% or 72.9-7.29=65.61
so after 4th dose only 65.61% are left
b. so to get it to 5% you do alot and find that it takes 27 tries to get the percent down to 5.2% and 28 doses to get it to 4.7%
