Answer 1

Explanation:

The program output is also shown below.

The program output is also shown below.* C++ Program to Compute the Area of Circle.

The program output is also shown below.* C++ Program to Compute the Area of Circle.float radius, area;

The program output is also shown below.* C++ Program to Compute the Area of Circle.float radius, area;std::cout << "Enter the radius of circle : ";

The program output is also shown below.* C++ Program to Compute the Area of Circle.float radius, area;std::cout << "Enter the radius of circle : ";std::cin >> radius;

The program output is also shown below.* C++ Program to Compute the Area of Circle.float radius, area;std::cout << "Enter the radius of circle : ";std::cin >> radius;area = 3.14 * radius * radius;

The program output is also shown below.* C++ Program to Compute the Area of Circle.float radius, area;std::cout << "Enter the radius of circle : ";std::cin >> radius;area = 3.14 * radius * radius;std::cout << "Area of circle with radius "

The program output is also shown below.* C++ Program to Compute the Area of Circle.float radius, area;std::cout << "Enter the radius of circle : ";std::cin >> radius;area = 3.14 * radius * radius;std::cout << "Area of circle with radius "<< radius << " is " << area;

Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. (Square inches can also be written in2.)
