Question

A cylindrical water tank has a radius of 15 cm and filled with water to a depth of 35cm. If 200cm^3 of water was used for washing clothes, find the volume of water left in the cylinder. Take π as 22/7

Answer 1

Answer:

24550 cm^3

Step-by-step explanation:

Vol of 35 cm deep water in tank = $\pi r^{2} h = \frac{22}{7} * 15 * 15 * 35 = \pi *7875 =24750 cm^{3}$

Vol of water left = 24750 - 200 = 24550 cm^3

Answer 2

Answer:

Volume of Cylindrical water tank =  π$r^{2}$h

r = radius of cylindrical water tank = 15 cm

h = height of cylinder ( here  we take  depth of water) = 35 cm

⇒ Volume of water = 22*15*15*35/7 = 24750 $cm^{3}$

⇒ water used for washing clothes = 200 $cm^{3}$

⇒ volume of water left in the cylinder = 24750-200 = 24550  $cm^{3}$
