13. There is a circular flower bed of radius 30 m. There is a 10 m wide running
track around it. What is the area of the running track?​

Answer 1

Answer:

Radius of the flower bed = 30m

Area = 22/7*30*30 m^2

=19800/7sq.m.

Radius of remaining bed = 30-10=20m

Area = 22/7*20*20 sq. M.

= 8800/7 sq. M.

Area of path =total area - area of remaining bed.

So,

Area of path= 19800/7 - 8800/7 sq. M.

= 11000/7 sq. M.

=1571.428 sq. M. (approximately).

Hope this will be helping you.
