Formula for area of circle (shape of pizza):
______________________________________________________
A =
* r² ;
in which: "A = area of the pizza (area of a circle)" ; for which we are to solve.
"" = 3.14 (approximation we shall use) ;
r = radius = "d/2" ; d = diameter = 18.5 in (given) ;
r = d/2 = (18.5 in. / 2) = 9.25 in.
_______________________________________________
Plug our known values into the formula to solve for "A" (area):
A = * r² ;
= (3.14) * (9.25 in)² ;
= (3.14) * (9.25)² * (in²) ;
= (3.14) * (85.5625) * (in²) ;
= 268.66625 in² ;

Round to: " 268.666 in² " .
