Question

The area of circular swimming pool is 154m2.Find out the radius if the swimming pool.

Answer 1

Answer:

radius=7m

*EXPLANATION*

area of circular swimming pool=154m^²

(area of circle=π r^²)

Therefore,

area of circular swimming pool=πr^²

154=πr^²

154=22/7r^²

154*7/22=r^²

7*7=r^²

49=r^²

√49=r

r=7m
