5. The formula to compute the area of a circle is: Area Ar where r is the radius of the circle and is 3.1416. Assume a variable radius has already been declared (type double) and initialized with the value of the radius of a circle. Write C++ statements to do the following: Declare a constant Pl and initialize it to 3.1416 Declare a variable volume of type double Calculate the area of the sphere and store it in the variable area. Display the computed area on the console. 5. The formula to compute the area of a circle is: Area Ar where r is the radius of the circle and is 3.1416.
