The correct answer is
C.)
Step-by-step explanation:
We can divide the total volume of the silo into two :
A cylinder with a radius of 2 ft and height 10 ft
And a cone with a radius of 2 ft and height 3 ft
The volume of a cylinder with radius R and height H is :
The volume of a cone with radius R and height H is :
In the exercise, the volume of the cylinder with radius 2 ft and height 10 ft is :
The volume of the cone with radius 2 ft and height 3 ft is :
Rearranging the expression :
In the expression, we write the height of the cone as the difference between 13 ft and 10 ft
The correct option is option C.)
