Question

If a spool for thread is 2 cm in diameter then one wind of thread is about how many centimeters long? Use 3.14 for pie

Answer 1

Answer:

6.28 cm

Step-by-step explanation:

One wind of thread is the circumference of the circular spool.

Th circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

here d = 2 cm and using 3.14 for π , then

C = 3.14 × 2 = 6.28 cm

One wind of the thread is 6.28 cm long
