Answer:
8 interior angles
Step-by-step explanation:
- There is a simple trick to finding the number of interior angles
- For instance, a triangle has 3 sides, and how many angles are in a triangle? 3
- A square has 4 sides and 4 interior angles
- A pentagon has 5 sides and 5 interior angles
- So an octagon, the shape we have here, has 8 sides so 8 interior angles

A = πr²
A = π7²
A = 49π
A = 49.3,14
A = 153,86
Rounding to the nearest tenth
A = 153,9 cm²
