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.
