1.	0. The circumference of a circular plot is 220 m. A 15 mwide concrete track runs round outside the plot. Find thearea of the track. Use Ď = 22m
Answer» Let the radius of the circular plot be xcircumference = 2202 x 22/7 x x = 220x = 35Nownew radius = 35+ 15 =50marea = 22/7(50^2-35^2)=1275 [approx]
