Question

The diameter of a circle is 8 inches.

(a) Find the area of the circle
(b) Find tye circumference if the circle

Answer 1

(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

Answer 2

Diameter= approx. 50.27
Circumference= approx. 25.13
