Given : The Ink Container is Cylindrical in shape
Given : The Height of the Ink Container is 14 cm
Given : The Radius of the Ink Container is 6 cm
Let us find the Volume of the Ink Container :
★ Volume of a Cylinder is given by : π × (Radius)² × (Height)
We know that : Ballpen refill is Cylindrical in shape
Given : The Length of the Ballpen refill is 12 cm
Given : The Inner Diameter of the Ballpen refill is 2 mm
● As Radius is Half of the Diameter :
The Radius of the Ballpen refill is 1 mm
★ We know that : 1 mm = 0.1 cm
The Radius of the Ballpen refill is 0.1 cm
Let us find the Volume of One Ballpen refill :
In order to solve the Problem : We need to realize that Volume of the Ink in the Container before filling in the Ballpen refills should be equal to Volume of Ink in the Total Number of refills which are filled. Because : Total Volume of the Ink remains Constant.
Let the Number of Ballpen refills filled with Ink be : R
