Answer:
Volume of round cake pan = volume of cylinder
Volume of a cylinder = (where r is the radius and h is the height)
Radius = diameter ⇒
⇒ volume of round cake pan =
= 76.97 in³ (nearest hundredth)
Volume of rectangular cake pan = volume of rectangular prism
volume of rectangular prism = (where w is the width, l is the length and h is the height)
⇒ volume of rectangular cake pan = 6 x 9 x 2 = 108 in³
As 108 > 76.97, the rectangular cake pan has a larger volume
