He found that after being conditioned, the dog salivated every time he heard the bell ring, the salivation was now a conditioned response.
Area formula for a circle is pi *r^2
circumference is pi * d
22.6/3.14 is 7.197= diameter
radius= 3.5985
pi * (3.5985)^2 =40.66
area is about 40.66 square inches
