i think i am wrong ​

Answer 1

Answer:

Step-by-step explanation:

Given that height (h) of the conical vessel = 11 cm Radius (r1) of the conical vessel = 2.5 cm Radius (r2) of the metallic spherical balls = 0.52 = 0.25 cm Assume the number of spherical balls that were dropped in the vessel as 'n'. Volume of the water spilled out of the vessel = Total volume of the spherical balls dropped 25 × Volume of the cone = n × Volume of each spherical ball ⇒25 × 1/3 πr12h = n × 4/3 πr23 ⇒r12h = n × 10r23 ⇒ (2.5)2 × 11 = n × 10 × (0.25)3 ⇒ 68.75 = 0.15625 n ⇒ n = 440. ∴The number of spherical balls that were dropped in the vessel is 440. Sushant made the arrangement so that the water that flows out, irrigates the flower beds. This shows the importance of conservation of water.

Sorry for continuous text answer is 440 balls
