Answer :
Final answer:
The perimeter of each piece of the circular cake is approximately 78.5 cm.
Explanation:
To find the perimeter of each piece of the circular cake, we need to find the circumference of each quarter. The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter.
In this case, the diameter of the cake is 25 cm, so the circumference is C = π(25 cm). Using the approximation of π as 3.14, the circumference is 3.14(25 cm) = 78.5 cm. Therefore, the perimeter of each piece is approximately 78.5 cm.
