Write a function that accepts the radius, r, of a circle and returns its area, A. Recall that if r represents the radius of a circle then its area is determined by A=PIr2. where PI=3.1412 is a universal constant. The schematic above shows a partially full array, named aNums. It contains age data from patients records from a hospital. There are some valid and some invalid data. Assuming 1 is the impossible value and that a valid data is something in the range 1 to 110 , write a loop with a condition to eliminate the invalid data. Note that this is impossible-value PFA problem. Which of the provided functions (given at right) would be called in each of the following lines of code (listed at left). x Fn(new int [10]): xFn(T0); 1. void x Fn(char s)(...) 2. String Fn( String s)(...) xFn("Hello"); 3. void x Fn(int []x)(] xFn("Hello, |c'"')
