(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
