Answer 2

Answer:let the inner circumference be c and outer circumference be C

Let the inner radius be r and outer radius be R

Step-by-step explanation:

c=2πr=176

=>r=176*7/2*22

=r=28

R=r+7=35

Area of track = π(R^2-r^2)

=(22/7)(1225-784)

=1386sq.m.

Cost of fencing =2πR*rate

=2*(22/7)*35*12

=Rs.2640
