Answer 1

1.57

Explanation:

Circumference=2pi r

=2x3.14x.25

=1.57

Answer 2

C = .5 pi inches

If we approximate pi by 3.14

C =1.57 inches

If we approximate pi by the pi button

C =1.570796327 inches

Explanation:

The circumference of a circle is given by

C = 2* pi *r

C = 2 * pi * .25

C = .5 pi

If we approximate pi by 3.14

C =1.57 inches

If we approximate pi by the pi button

C =1.570796327 inches
