Answer:
see below
Step-by-step explanation:
First we need to find the radius
r =d/2 = 15.8/2 = 7.9 cm
The area of a circle is given by
A = pi r^2
    = pi ( 7.9) ^2
    =62.41 pi
Using 3.14 for pi
195.9674  
To the nearest hundredth
195.97
Using the pi button
196.0667975
To the nearest hundredth
196.07
