Answer» Volume of a sphere = \(\frac{4}{3}\)πr3 Given, Measuring jar of internal diameter 10 cm is partially filled with water. Four equal spherical balls of diameter 2 cm each are dropped in it and they sink down in water completely. Let the rise in level of water be ‘h’ cm. ⇒ π x 52 x h = 4 x \(\frac{4}{3}\)π x 13 ⇒ h = \(\frac{16}{75}\) cm |
