Answer:7.1 feet^2

Step-by-step explanation:The base is made of a circular shape, so to solve this question we need to know how to calculate the circle area. The formula for the circle area is π * r^2 so we need to find the radius(r). Radius equal to half of the diameter and the diameter needed is 3 feet, then the area of the circle will be:

area = π * r^2

area = 3.14 * (3/2 feet)^2

area = 7.065 feet^2 = 7.1 feet^2
