Yes both of the two fraction are proportion
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° =
=
= 
Multiply both sides by 7, thus
AC = 7sin40° → A
It would bw 12 99/100 and then 1299/100
3×3=9 miles. As a result, hiker traveled total 9 miles in that time. Hope it help!
Solution
A=4πr2=4·π·82≈804.24772
Approximately = 804.25
