Solving quadratic equations:

What is the radius of the largest circular quilt that can be made with an area less than or equal to 70 ft^2? Round your answer to the nearest tenth of a foot if necessary.

Please solve and explain. Thanks

  • Alg 1 -

    A = pi * r^2

    70 = 3.14 * r^2

    70/3.14 = r^2

    22.29 = r^2

    4.72 =< r
