A wire of length 25m is to be cut into two pieces one of the wires is to be made into square and other into a circle. What should be the length of two pieces so that the combined area of the square and the circle is minimum?
- \(\frac{2 \pi}{\pi+4} \cdot \frac{4 \pi}{\pi+4}\)
- \(\frac{25 \pi}{\pi+4} \cdot \frac{100}{\pi+4}\)
- \(\frac{6 \pi}{\pi+4}, \frac{8 \pi}{\pi+4}\)
- none of these
Answer
(B) 25 +4 100 +4
