the diameter of a circular Park is 66 metre outside the park there is a path 4 metre wide running around it find the cost of turfing the path at rupees 2.50 per square metre ​

Answer 1

Answer:

10.00rupees

path =4m

per square mt turfing!=2.50×4=10.00

Answer 2

Area of the path:

πR2-πr 2

π(R2-r2)

R=33 +4 = 37m

r=33m

A=22/7 (37^2-33^2)

= 22/7x280

= 22x40=880m2

cost of turfing=880x2.5=Rs.2200
