Answer 1

Answer:

see below

Step-by-step explanation:

The circumference of a circle is given by

C = pi * d

C = pi * 26

C = 26pi

We can approximate pi = 3.14

C =81.64 inches

or we can approximate pi by using the pi button

C =81.68140899 inches

Using the choices listed and approximating pi as 3

C = 3*26 = 78 inches
