Answer:
c. (Multiply 4 by the difference of 10 and 3, then add 5)
Answer:
10.5 ft.
Step-by-step explanation:
1. Find the radius of the larger circle
4/7 = 3/r --> the ratio should be <em>constant</em>
cross-multiplication: <em>21 = 4r</em>
Divide: <em>r = 5.25 ft.</em>
2. Find the circumference
Equation: <em>C = 2πr</em>
C = <em>2π*5.25</em>
C = 10.5π ft.
Time it by the number before hand and you get 8 then 16 then 32 . Think about it it works and it’s a consistent continental
