Answer 1

hey mate ........
here is ur answer ........
______________________

length= 14 cm

angle= 5 * 6 = 30 degree                    {because, angle swept in 1 min = 60/360 = 6 degree}

area swept = 30/360 * 22/7 * 14 * 14

                    = 1/12 *22 * 2 * 14

                    = 154/3

                    = 51.33 cm^2
