Question

21.The water for a factory is stored in a hemispherical tank whose internal diameter is 14m. The tank

already contains 250 kilo litres of water. More water is pumped into the tank to fill to its capacity.

Find the volume of water pumped into the tank [ use π = 22 / 7].​

Answer 1

Answer:

value is 13 find the value of water is pumped into the rank is value of 13

Answer 2

Answer:

668.67 m³

Step-by-step explanation:

Radius of hemispherical tank, r=7 m

So volume of water to be pumped = Volume of hemispherical tank −50 kl

Therefore, 1 kl = m³

⇒ 2/3 πr³ - 50 m³

⇒2/3 × 22/7 × (7)³ - 50 m³

⇒718.67 m³ - 50 m³

⇒668.67 m³
