When baking a cake, you have a choice of the following pans: a round (cylindrical) cake pan that is 3 inches deep and has an 8 inch diameter or an 8 inch × 11 inch rectangular cake pan that is 3 inches deep. Which of these pans has the larger volume?
The cylindrical cake pan has a larger volume.
To find the volume of the cylindrical pan, we use the formula: V = πr^2h, where r is the radius and h is the height.
We know that the diameter is 8 inches, so the radius is 4 inches.
V = π(4^2)(3) = 48π cubic inches
To find the volume of the rectangular pan, we simply use the formula: V = lwh, where l is the length, w is the width, and h is the height.
V = (8)(11)(3) = 264 cubic inches
48π is approximately equal to 150.8 cubic inches.
Since 150.8 cubic inches is less than 264 cubic inches, the cylindrical cake pan has the larger volume.
