The largest square that can be drawn in a circle has a side whose length is 0.707 times the diameter of the circle. By this rule, find the length of the side of such a square when the diameter of the circle is
(a) 14.35 cm (b) 8.63 cm
(a) 10.15 cm
(b) 6.10 cm
Side \(=0.707\times d\). (a) \(0.707\times14.35\approx10.15\) cm. (b) \(0.707\times8.63\approx6.10\) cm.
