You need to find the area of a circular base.
The formula for area of a circle is pi x r^2.
Just plug in the information that you are given.
A=3.14 x 1.5^2
Solve.
A=7.065
Round to the nearest tenth.
7.1 ft^2 of turf need to be painted for one base.

Geometry:
In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles. It can also be defined as a rectangle in which two adjacent sides have equal length. A square with vertices ABCD would be denoted \square ABCD.
Square Roots:
In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16.
