Answer:
f(2.11) = 13.9867 or 13.99 in²
Explanation:
Given the radius ( r ) of 2.11 inches, we can determine the area of a circle by substituting the value of the radius into the following function:
f(r ) = πr²
f(2.11) = π(2.11)²
f(2.11) = π(4.4521)
f(2.11) = 13.9867 or 13.99 in²
Therefore, the area of the circle with a radius of 2.11 inches is 13.99 in².
