Do the area of the circle as a whole minus (72/360 x radius^2) and then minus the other grey area.
Answer:
19 Lollipops per friend
Step-by-step explanation:
It takes 45 minutes because if you do 6 divided by 2 you get 3 and then you do 3 x 15 you get 45. So 45 is your answer
All are equal except A/D = C/B
I replaced the values with numbers
a=5 b=10 c=50 d=100
10/5=100/50 so it’s not b/a = d/c
5/10=50/100 so it’s not a/b = c/d
5/50 = 10/100 so it’s not a/c = b/d
5/100 is NOT 50/10 so it’s NOT a/d = c/b
