Answer:
A. 3:8
Step-by-step explanation:
Circumference of smaller circle = 12π cm
Circumference of larger circle = 32π cm
Formula for circumference = 2πr
✔️Radius (r) of smaller circle:
12 π = 2πr
Divide both sides by 2π
12π/2π = (2πr)/2π
6 = r
r = 6 cm
✔️Radius (r) of larger circle:
32 π = 2πr
Divide both sides by 2π
32π/2π = (2πr)/2π
16 = r
r = 16 cm
✔️Ratio of radius of smaller circle to the radius of leather circle:
6:16
Simplify
3:8
