Answer:
66mm
Step-by-step explanation:
A diagram of a coin is shown.
Radius = 10.5 mm
The approximate circumference of the coin is calculated using the formula
2πr
Use 3.14 as an estimate for it.
r = 10.5mm
Hence:
2 × 3.14 × 10.5
= 65.94
Approximately = 66mm
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm
