ABCD is a square with one vertex at the center of the circle and two v

1.	ABCD is a square with one vertex at the center of the circle and two vertices on the circle.What is the length of AC if the area of the circle is 616 cm2?(a) 14 cm(b) 14V2 cm(c) 28 cm(d) 28V2 cm
Answer» πr² = 616 r² = 616*7/22 r = √196 r = 14m diagonal² = 14²+14² diagonal = √392 diagonal = 14√2 cm plz send me details

Answer»

πr² = 616

r² = 616*7/22

r = √196

r = 14m

diagonal² = 14²+14²

diagonal = √392

diagonal = 14√2 cm
