In this problem, you are measuring the length of a knitting needle by reading the scale at both ends. To find the length of the needle, you subtract the smaller reading from the larger reading.
Given:
Reading at one end = 3.0 cm
Reading at the other end = 33.1 cm
To calculate the length of the needle, use the formula:
Length of the needle = Reading at the other end – Reading at one end
Substitute the given values into the formula:
Length of the needle = 33.1 cm – 3.0 cm
Length of the needle = 30.1 cm
Therefore, the length of the knitting needle is 30.1 centimeters.
