<span>So we want to know what the area of a circular bread is if we know the diameter d=11 inches. First the diameter is equal to 2 radii, d=2r, so our radius r=11/2=5.5 inches. Now we can calculate the area. Formula for the area is A=pi*r^2. After we input our numbers we get the area A=94.985inches^2. Rounding the answer to the nearest hundreth: A=94.98 inches ^2</span>
