Answer:
(A) 50.24 square inches
(B)25.14 is the circumference
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
