    Answer:

    The approximate length of the radius, r is 12 inch.

    Step-by-step explanation:

    Given:

    A circle P is given having circumference C,

    C = 75 inch

    pi = π = 3.14

    radius = r

    To Find:

    radius = r = ?

    Solution:

    Circumference:

    In geometry, the circumference (from Latin circumferens, meaning “carrying around”) of a circle is the (linear) distance around it.

    That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.

    Formula is given as

    Circumference=2\pi (radius)

    Substituting the values we get

    75 = 2 × 3.14 × r

    r =\frac{75}{2\times 3.14}\\ \\r=\frac{75}{6.28} \\\\r=11.942\ inches

    We approximate radius to

    radius = 12 inich
