<u>113.04 ft2</u>
Step-by-step explanation:
r=d/2=12/2=6
A= pi*r*r=3.14*6*6
A=113.04
Domain: 
Range:
Explanation:
The function is 
The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function is defined in the interval .
The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function is defined in the interval .
