    Answer:

    c=2pir

    15.7=2pir

    divide by 2

    7.85=pir

    divide both sidse by pi

    7.85/pi=r

    ok so

    area=pir^2

    area=pi(7.85/pi)^2

    area=pi(61.6225/(pi^2))

    area=61.6225/pi

    use 3.14 for pi

    area=61.6225/3.14

    area=19.625 square units

    Hope it helped <3
