A spool of thread contains 150 revolutions of thread. The diameter of the spool is 3 centimeters. Find the length of the thread to the nearest centimeter.
Steps please thanks.
Circumference of circle = 2 x radius x pi
Diameter= 2 x radius = 3 cm
pi = 3.14
So circumference = 3 x 3.14 = 9.42 cm
There are 150 revolutions, so answer is 150 x 9.42 = 1413 cm
