Question 1018612
.
The area of a circle of radius r is given by the polynomial pie r^2. Where pie is an irrational number. 
Use 3.14 as an approximation of pie, and find the area of a circle with radius 3 cm 
--------------------------------------------------


Area = {{{pi*r^2}}} = {{{3.14*3^2}}} = {{{3.14*9}}}.


Please calculate it yourself.
