A wire of length 2 units is cut into two parts which are bent respectively to form a square of side = x units and a circle of radius = r units. If the sum of the areas of the square and the circle so formed is minimum, then:
- \(2 x=(\pi+4) r\)
- \((4-\pi) \times=\pi r\)
- \(x=2 p\)
- \(2 x=1\)
Answer
(A) 2 x=( +4) r
