    Answer:

    R = 161.917872904

    Step-by-step explanation:

    formula for circles circumference is , C = 2*pi*R

    so we work backwards now we plug in circumference

    1017.36 = 2*pi*R

    508.68 = pi*R

    R = 161.917872904

    SO radius is R = 161.917872904

    Answer:

    \huge\boxed{162\ units}

    Step-by-step explanation:

    \text{The formula of a circumference of a circle:}\\\\C=2\pi r\\\\r-radius\\\\\text{Substitute}\\\\C=1,017.36\\\\1,017.36=2\pi r\qquad\text{divide both sides by}\ 2\pi\\\\\dfrac{1,017.36}{2\pi}=\dfrac{2\pi r}{2\pi}\\\\r=\dfrac{508.68}{\pi}\qquad\text{use}\ \pi\approx3.14\\\\r\approx\dfrac{508.68}{3.14}\\\\r\approx162
