    7,539.14

    Step-by-step explanation:

    To solve for area, square the radius (radius times radius) then multiply by 3.14.

    A=pir^2

    The diameter is 98mm

    pi = 3.14

    r = 49^2=

    49 X49 = 2,401

    2,402 X 3,14 = 7,539.14

    A = 7539.14 mm^2

    Step-by-step explanation:

    Area of a circle is given by

    A = pi * r^2

    We need to know the radius

    r = d/2

    r = 98/2

    r = 49 mm

    The radius is 49 mm and pi = 3.14

    A = 3.14 * (49) ^2

    A = 7539.14 mm^2
