Answer:
The cakes radius is 5 inches.
Step-by-step explanation:
- cake has a circular area.
- Therefore we will use, area of circle: πr²
- Here given the cake is cut in six equal size.
- The area of the slice will be
(πr²)
Steps:
→
πr² = 13
→ πr² = 13(6)
→ πr² = 78
→ r² =
→ r =
→ r = 4.982787485
→ r = 5
Therefore the cake has a radius of 5 inches. Do not misunderstand that we are taking slice radius, its the radius of the cake all along.
