Guide to Solving Exercise 3 Page 106 Math 5 Textbook
Problem Statement:
A thread connects two pulleys (as shown in the figure). The diameter of the pulleys is 0.35m. The two axles are 3.1m apart. Calculate the length of the thread.
Solution method:
Students should note: The length of the thread equals the sum of the lengths of two half-circles (equal to the circumference of the circle) plus 2 times the distance between the two axes.
- Step 1: Calculate the circumference of the circle with a diameter of 0.35 meters by multiplying the known diameter by the value of pi (3.14).
- Step 2: Calculate the length of the thread by adding the circumference of the circle with a diameter of 0.35 m to 2 times the distance between the two axes.
Answer:
The circumference of the circle with a diameter of 0.35m is:
0.35 x 3.14 = 1.099 (m)
The length of the thread is:
1.099 + 3.1 x 2 = 7.299 (m)
Answer: 7.299m.
