Ms. Dolinski is making cakeas! She measured the entire length of the square cake and found that the perimeter w 20 inches. On the circular cake, she found that the circumference was 25 inches (Drawings not to scale!)

What is the area of the square cake?

What is the area of the circle cake? (Use 3.14 for Pi)

Which cake is larger? (type in 'square' or 'circle')

What is the difference between the larger cake and the smaller cake?
