Answer 2

The inner and outer circumferences of track are 176m and 264m
so radius of inner circle=?
circumference is 176
176=2*22/7*radius
176=44/7 *radius
radius=176*7/44
radius=28cm


radius of inner circle=?
circumference is 176
176=2*22/7*radius                              area of iner circle=22/7 *radius*radius
176=44/7 *radius                                                             =2464m²
radius=176*7/44
radius=28cm             
                                  

radius of outer  circle=?
circumference is 264                  area of outer circle=22/7*radius²
   264=*22/7*radius                                                   =5544m²
 264 =44/7 *radius
radius=264*7/44
radius=42cm

area of path=area of outercirlce-inner circle
                               =5544-2464
                                   =3080m²
