    (A) 50.24 square inches

    (B) 25.14 is the circumference

    Step-by-step explanation:

    (A) Diameter of circle = 8 inches

    so radius of circle = 4 inches

    now area = π r^2

    =3.14 * 4*4

    = 3.14*16

    = 50.24 square inches (Ans)

    (B) R a d i u s o f c i r c l e = 4

    C i r c u m f e r e c e = 2 π r = 2 π (4) = 8 π

    = 8 * 22 / 7 = 176 / 7 = 25.14
