Below are three easy questions dealing with circles, distances
and their areas etc. Venkatanarayana Road, T.Nagar, Chennai
600017 has a playground that is circular in shape. Mukesh
started running in clock wise direction from point X. Anil
started running from point X in anti-clockwise direction. Mukesh
ran 550 m and Anil ran 330 m before they met each other. What is
the area of this ground? a) pi x 16.9 x 102 m2 b) pi x 1.97 x
102 m2 c) pi x 19.6 x 102 m2 d) pi x 1.69 x 102 m2 Answer : c)
pi x 19.6 x 102 m2 Circumference of a circle = 2 x 22/7 x radius
Mukesh has run 550 m and Anil has run 330 m before they met. So
the circumference of the circle would be the sum of the
distances they covered = 550 m + 330 m = 880 m. Circumference =
880 m = 2 x 22/7 x R R = 880 x 7 divided by 2 x 22 = 140 m. Area
= pi x R2 = pi x 19.6 x 102 Cubbon Park, Bangalore has a
circular garden inside it constructed hundreds of years ago.
Bangalore Corporation has been maintaining this garden nicely.
