Answer:
The volume of the marble is 47 ml
The volume of the water is 100 ml
Step-by-step explanation:
we know that
The volume of the marble is equal to the change in water level

To find out the volume of the marble subtract 100 ml from 147 ml
The volume of the water no change
The volume of the water is 100 ml

Answer:
h = 9x
Step-by-step explanation:
Given: i. for the cylinder, base radius = 2x cm, height = h cm
ii. for the sphere, radius = 3x cm
iii. volume of the cylinder = volume of the sphere
volume of a cylinder is given as;
volume = h
where: r is its base radius and h the height
volume of the given cylinder = x
x h
= x 4
x h
= h
volume of a sphere =
where r is the radius.
volume of the given sphere = x
= x 9
= 12
Since,
volume of the cylinder = volume of the sphere
Then we have;
h = 12
4 h = 36
subtract from both sides
4h = 36
x
divide both sides by 4
h =
= 9x
h = 9x
