    22 feet will be the length of ribbon.

    Step-by-step explanation:

    Joshua was sewing a circular tablecloth for his grandmother. He wants to sew a ribbon around the edge of the tablecloth.

    So to measure the length of ribbon will be the the perimeter of the circular cloth.

    Perimeter of a circle = 2π r

    Therefore perimeter of table cloth = 2*π*3.5 = 7π

    = 7 * 3.14 = 21.98 feet ≅ 22 feet
