    We are to solve for the value of the altitude of the given cylinder which has a radius of 5 feet and a lateral area of 70pi ft². To solve this we should recall that the formula in solving the lateral area of a cylinder is Lateral Area = 2pi*r*h. The solution is shown below:

    r is equal to 5 ft

    lateral area = 70pi

    Solving for h, we have:

    70pi = 2pi*5*h

    70pi / 2pi = 5h

    35 = 5h

    divide both sides by 5, we have:

    35/5 = 5h/5

    7 = h

    The answer for the length of the altitude is 7 feet.
