From statement I: Diagonal of the square = Diameter of the circular field Side of square = √6400 cm = 80 cm diagonal of square = √2 side = √2 × 80 = 80√2 cm So 80√2 = 2r So r = 80/√2 Hence Area of the circular field = πr2 = π×(80/√2)^2 = π×6400/2= 3200π cm2 From statement II: Side of a square = √4900 = 70 cm = diameter of circle So 2r = 70 or r = 35cm Area of circular field = πr2 = π×352 = 1225π cm2 So answer can be determined by either of statement I or II.
A swimmer swims from a point A against a current for 5 minutes and then swims current for next 5 minutes and comes to the point B. If AB is 100meters, t...
Ratio of speed of boat in downstream and speed of stream is 5:3, if speed of current is 9 km/hr, then find distance travelled (in km) upstream in 8 hours.
A motorboat in still water travels at a speed of 16 km/hr. It goes 27 km upstream in 2 hour 15 minutes. The time taken by it to cover the same distance ...
The speed of a boat in still water is three times the speed of the boat upstream. If the boat takes 30 minutes to cover 27 km downstream, then find the ...
