Use the GCF to write it as a distributive property
First, we find the GCF of 75 and 45
The common factor is:
So, becomes
Factorize
<em>Hence, the sum has been rewritten as </em><em></em>
Volume:
A composite figure is formed by two or more basic figures or shapes. In this problem, we have a composite figure formed by a cylinder and a hemisphere as shown in the figure below, so the volume of this shape as a whole is the sum of the volume of the cylinder and the hemisphere:
So:
From the figure the radius of the hemisphere is the same radius of the cylinder and equals:
And the height of the cylinder is:
So:
The volume of a hemisphere is half the volume of a sphere, hence:
Finally, the volume of the composite figure is:
