A thin silver disc of diameter 10cm cost #3300.what is the cost per m
10 times as much, since 10(10 cm) = 1 m
To find the cost per meter of the thin silver disc, we need to first calculate the length of the silver disc and then divide the cost by this length.
The disc has a diameter of 10 cm, so the radius would be half of that, which is 5 cm (or 0.05 m).
The length of the disc can be obtained by calculating the circumference of the disc, which is given by the formula: C = 2πr, where C is the circumference and r is the radius.
Substituting the values, we have: C = 2 x π x 0.05 m ≈ 0.314 m.
Now, we can calculate the cost per meter by dividing the cost by the length:
Cost per meter = Cost / Length = #3300 / 0.314 m ≈ #10,509.55
Therefore, the cost per meter of the thin silver disc is approximately #10,509.55.
