    300 feet

    Step-by-step explanation:

    IF you multiply the radius by 2, then all 2-dimensional measurements will be doubled too. Because circumference is 2d, the new circumference = 2*150 = 300

    300 ft

    Step-by-step explanation:

    C = 2 * pi * r

    We double the radius

    = 2 * pi * 2r

    We will double the circumference

    = 2*pi*r * 2

    150 will become 300
