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 pi)
The total length of the silver wire used to make the chain is:
100 links x circumference of each link
= 100 x 2πr
= 100 x 2 x 3.14 x 2.5
= 1570 cm (rounded to the nearest whole number)
The cost of the silver wire used to make the chain is:
1570 cm x $60/cm
= $94,200
Therefore, the value of the chain is $94,200.
