Answer:

C = 96.71 inches

A = 745.06 in ^2

Step-by-step explanation:

d = 30.8

The radius will be 1/2 d=   1/2 (30.8) = 15.4

The circumference = pi *d

                                 = pi * 30.8

                                  =96.761

The area = pi * r^2

                = pi * (15.4)^2

                = 745.06011
