How many circular plates of diameter d be taken out of a square plate of side 2d with minimum loss of material ?
-
- 8
- 6
- 5
- 2
Correct Option: C
Area of square plate = (Side)2
= (2d)2
= 4d2
Area of circular plate = π (d/2)2
= πd2/4
∵ Number of square plates
= [(4d2)/4] / [(πd2)/4]
= (4 x 4)/π
≈ 5
Since, nearest integer value is 5.
