Answer:
r = 40/π exact answer
r = 12.7 decimal approximation
Step-by-step explanation:
arc length formula
s = (∅/360) * 2πr
s = (∅/180) * πr
--------------------------------
Plug in the givens
10 = (45/180) * πr
10 = .25πr
Divide both sides by .25
40 = πr
divide both sides by π
40/π = r
r = 40/π exact answer
r = 40/3.14
r = 12.7 decimal approximation
Um what if you multiply 2.5 x5=12.5 then multiply 16x3=48 and then subtract 12.5 by 48 and you will get 77 cups of sugar srry if it is not the right answer this is not my account this is my fathers im not in collage im in 5th grade . so i hope this helped you
