Answer 1

Answer:

volume of one marble=1.54 cubic cm

volume of water with height5.6cm=215.6 cubic cm

no. of marbles = 215.6/1.54

=140

Answer 2

Answer

75 marbles

Step by step solution

Diameter of sphere = 1.4cm

Volume of sphere =

$4 \div 3 \times \pi \times {1.4}^{2}$

=> 11.49 cm³ . . . (1)

Diameter of cylinder = 7cm

Height of water level to rise = 5.6cm

Volume of Cylinder =

$\pi \: \times {7}^{2} \times 5.6$

=> 862.05cm³ . . . (2)

No. of marbles required => (1) / (2)

$862.05 \div 11.49$

=> 75.02 or 75 (approx)
