    Answer:

    ₹15,092

    Step-by-step explanation:

    Given, d = 98 meter

    therefore, r = 98/2 = 49

    area of the circular field is ——>

    = π × r × r

      =  \: \frac{22}{7}  \times 49 \times 49

     =  \: 22 \times 7 \times 49

     =  \: 7546

    therefore, the cost of cleaning the whole field is 7546 × ₹ 2.7

    = ₹ 15,092.

    answer

    20374.2 Rs

    Step-by-step explanation:

    diameter of the circular field = 98m

    radius of the circular feild = 98/2 = 49m

    area of the circular field = πr^2

    = 22\7 × 49^2

    =22/7 × 49 × 49

    = 22 × 7 × 49

    = 7546m^2

    cost of cleaning the field per metre square = 2.7 Rs

    cost of cleaning the full circular field = 2.7 × 7546

    =20374.2 Rs
