With the Solve App individual or related equations can be easily solved. This process can as often as necessary be repeated, with the value of one or more variables in the equation changed or the equation can be solved for another variable.
We look for the volume V of a right circular cylinder with a height of H = 10 m and a surface area of m = 25 m, which applies to the lateral surface m and the volume V: m = 2 · π · R · H and V = R · R · π · H (R = radius and h = height of the cylinder).
In the symbol -view the formulas for the surface and the volume can be entered and Equation 1 is activated.
In the Num -view the given values are entered, the variable R is selected and its value is calculated using the "Solve" button.
After moving to the symbol -view Equation 1 is disabled and Equation 2 enabled.
In the Num -view the height and the previously determined radius R are already available. Solving for V leads to the desired result.
