For a, you could use the volume of a sphere divided by two to solve for a dome (like when you cut a sphere in half).
For b, you could use the volume of a rectangular prism divided by three when solving for a rectangular pyramid.
This is because the volume for a rectangular prism is V=lwh, and for a rectangular prism the volume is V= (1/3)lwh
The expression of the ratio is 150:3
In the context of data models, relationships among records in a hierarchical model are called Branches. This is further explained below.
<h3>What
are data models,?</h3>
Generally, The act of generating a visual representation of either a whole information system or portions of it in order to express the linkages between different data points and structures is known as data modeling.
