Amount of water flowing from pipe in 1s = 6 × area of cross section of the pipe
= 6 × πr²
= 6 × 22/7 × 35/100 × 35/ 100
= 3× 11 ×7/ 100
3×7×11 Μ³ of pool is filled in= 1 s
I m³ of pool is filled in = 1/ 3× 11 × 7
70 × 44× 3 m³ of pool is filled in = 70 × 44× 3 /3× 11 × 7 = 4000s = 4000/ 60 × 60 = 1.11 hrs
= 6 × πr²
= 6 × 22/7 × 35/100 × 35/ 100
= 3× 11 ×7/ 100
3×7×11 Μ³ of pool is filled in= 1 s
I m³ of pool is filled in = 1/ 3× 11 × 7
70 × 44× 3 m³ of pool is filled in = 70 × 44× 3 /3× 11 × 7 = 4000s = 4000/ 60 × 60 = 1.11 hrs
