<u>Answer:</u>
The volume of cylinder in terms of π is
cubic feet
<u>Explanation:</u>
Given the radius of the cylindrical shaped concrete column is 3 feet
Height of the column is 15 feet
The volume of a cylinder is calculated by the formula;
V =
, where
r is the radius and h is the height
Substituting the values,
V = 
V = 

Hence, the volume of cylinder in terms of π is
cubic feet
10y + 20 is an equivalent expression
each interval represents 1 unit
