    area of a sqaure = πr^2 =154cm^2

    => r^2=154*7/22=7*6cm

    => r=7cm

    Answer:

    Ok

    Step-by-step explanation:

    Here,

    Area(a)= 154cm^2

    then

    we know

    area=πr²

    or, 154= \frac{22}{7}*r²

    or, 154*7=22r²

    or, 1078=22r²

    or, \frac{1078}{22}=r²

    or, 49=r²

    or, √49=r     (square becomes root when turned in another side)

    So, Radius is 7 ans!!

    HOPE IT HELPS!!!

    CAN I BE BRAINLIEST PLEASE/?

    THANKYOU!!
