Answer 1

Let the lever of water in the pona nses py 21 cm in t hours.

Speed of water = 15 km/hr

Diameter of the pipe = 14/100 m

Radius of the pipe (r) = 7/100 m Volume of water flowing out of the pipe in 1 hour

= πr²h

= (22/7) x (7/100) x (7/100) x 15000

= 231 m³

Volume of water flowing out of the pipe in t hours = 231 tm³.

Volume of water in the cuboidal pond

= 50 x 44 x (21/100)

= 462 m³

Volume of water flowing out of the pipe in t hours =

Volume of water in the cuboidal pond

So, 231 t = 462

t = 2

Hope it helps you and please mark me brainliest.
