Question

the inner circumference of circular race track is264 m and the width of track is 7 m.calculate the cost of putting up a fence along the outer Circle of the track at the rate 15 .(useπ=22/7)​ please solve this question

Answer 1

Answer:

inner radius= circumference/ 2π

so r= (264*7) / (2*22) = 42 m

hence outer radius = 42+7=49 m

outer circumference

= (2*22*49)/ 7

= 308 m

cost of putting fence

= 308 * 15= 4620
