solve this question and explained it very properly​

Answer 1

Answer:

☞Answer:

8800/7 sq. M.

☞Given:

circular flower bed of radius 30 m. There is a 10 m wide running track around it.

☞To Find:

area of the running track?

☞Solution:

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).

Answer 2

Answer:

M. Area of path =total area - area of remaining bed. So, Area of path= 19800/7 - 8800/7 sq.
