A proportion is an equation stating that 2 ratios are equal. One example of using them is in baking. An example of one would be:
Answer:
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

A budget is the amount of money you have to spend on something, you make a budget by taking your amount of money and choosing how much you want to save and how much you want to spend on something, and you balance your budget by possibly splitting your money then using half of it as the budget and half of it as saving
