Question

A silver chain has 100 links.each Link is made of thin silver wire and is in the shape of a circle of radius 2.5cm.find the value of the chain If the silver wire cost#60per centimeters.(use the value 3.14for n)

Answer 1

The circumference of each link is 2πr = 2π(2.5) = 15.7 cm.
Therefore, the length of wire used to make one link is 15.7 cm.
The total length of wire used to make 100 links is 15.7 cm/link x 100 links = 1570 cm.
If the silver wire costs #60 per centimeter, then the total cost of the wire used to make the chain is 1570 cm x #60/cm = #94,200.
Therefore, the value of the chain is #94,200.
