Question

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

the area of running track is fifty

Answer 2

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.
