please help...I'm totally confused with this introduction to c++ programming homework. 1st image is figure 9-2. thank you

How To Use the pow Function requires the #include Syntax directive pow(x, Example double cube 0.0 which is 4.0 raised to the third The assignment statement assigns the number 64.0, Cube pow (4.0, power, Example 2 power. The cout 0.5 number 10, which is 100 raised to the 0.5 the number 100. The statement displays the square root of pow(100, o. 5) expression is equivalent to finding the Example 3 double area 0.0; double radius 5.0 area 3.14 pow (radius, 2); the second The assignment statement raises the value stored in the radius variable to (785 to power, giving 25.0. It the multiplies the 25.0 by 3.14 and assigns the product the area variable.
