In the given figure, PQRS is a square and diameter of circle with cent
A. 308 cm2
B. 154 cm2
D. None of these
Right Answer is: A
Let the side of square be a cm.
then UO = a – and UP =
Now, in ΔOUP,
OU2 + UP2 = OP2
Hence, side of square PQRS is 14 cm.
Now area of circle circumscribed by square PQRS
Radius of such circle = √2a/2 = 14√2/2 = 7√2 cm.
Area = πr2=(22/7)×7√2×7√2 = 308 cm2
