    Answer: 87.96 cm

    Step-by-step explanation:

    Radius = √a/π

    =√616 / π = 14 cm

    Circumference = 2πr

    = 2 x π x 14

    = 87.96 cm

    Answer: 88 cm

    Step-by-step explanation:

    The area of a circle is A=πr². Since we know the area, we can use find the radius, and use the radius to find the circumference,

    616=πr²

    196=r²

    r=14

    Now that we have the radius, we can use it to find the circumference. The formula for circumference is C=2πr.

    C=2π (14)

    C=28π

    C=88 cm
