33 cubic centimetres of silver is drawn into a wire 1 mm in diameter.
33 cubic centimetres of silver is drawn into a wire 1 mm in diameter. The length of the wire in metres will be :
Answer/Solution
42 m
Steps/Work
Sol.
Let the length of the wire b h.
Radius = 1/2 mm = 1/20 cm. Then,
22/7 * 1/20 * 1/20 * h = 33 โ = [33 * 20 * 20 * 7 / 22] = 4200cm = 42 m.
Answer C
Let the length of the wire b h.
Radius = 1/2 mm = 1/20 cm. Then,
22/7 * 1/20 * 1/20 * h = 33 โ = [33 * 20 * 20 * 7 / 22] = 4200cm = 42 m.
Answer C
