Use function notation to represent the area of a circle with a radius of 2.11 inches

Sagot :

Answer:

f(2.11) = 13.9867 or 13.99 in²

Step-by-step 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 ) = π

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.
