Answer:
Step-by-step explanation:
break it down as many times as you can. how? just keep dividing each by 2. example: 85 divided by 2 is 42.5 so under both arrows put 42.5. then divide that by 2. 42.5 divided by 2 is 21.25. keep dividing until you cant no more
20% more than 80:
80 + 20% of 80
80 + 20/100 × 80
80 + 16
= 96
$14
20 x .7 = 14
C = 18
Put the numbers in place of their symbols and do the arithmetic. The diagram is showing you r = 3.
C = 2πr
C = 2(3)(3) . . . . . using 3 for π, as directed
