What is the area of each piece?

12) 25π/3 cm² ≈ 26.18 cm²

13) C. 2π m²

Step-by-step explanation:

Area of a sector is:

A = πr² (θ / 360°)

where r is the radius of the circle, and θ is the angle of the sector.

12) The diameter is 20 cm, so the radius is 10 cm.  The angle of each sector is 30°.  So the area is:

A = π (10 cm)² (30° / 360°)

A = 25π/3 cm²

A ≈ 26.18 cm²

13) To find the area, first find the radius using Pythagorean theorem.

a² + b² = c²

r² + r² = (4 m)²

2r² = 16 m²

r² = 8 m²

So the area is:

A = π (8 m²) (90° / 360°)

A = 2π m²

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
