Question

Rachel is baking a cake but does not know if she wants to make a round or a square cake which cake has a larger area a round 8 inch cake or a square 9 inch cake

Answer 1

The square cake has a larger area

Explanation:

Square cake

Area = L*L = (9inch*9inch) = 81 inch^2

Round cake

(8 inches corresponds to the diameter, so the radius is 4 inches)

Area = pi*(radius^2) = 3.1416*(8inch/2)^2 = 50.265 inch^2

Since 81 inch^2 > 50.265 inch^2

The Square cake has a bigger area
