Answer:
2.2.1 Area = 12.6 cm²
2.2.2 Area = 12 cm²
Step-by-step explanation:
<u></u>
<u>2.2.1:</u>
The radius of the big circle is half the length of the square = 2.5 cm
The radius of the small circle is half of 3 cm = 1.5 cm
The area of the shaded portion is = Area of big circle - Area of small circle
π × 2.5²-π × 1.5² = 12.6 cm²
<u>2.2.2</u>
To find length BD (the height of the parallelogram) we need to use the Pythagorean theorem:
BD = √(5²-3²) = 4
Area = base x height = 3x4 = 12 cm²

Answer:
height = (x^3 – 3x^2 + 5x – 3) / (x^2 – 2)
Step-by-step explanation:
We know that the volume of a rectangular prism is the product of its base area and height
Volume_prism = area_base * height
height = Volume_prism / area_base
Volume_prism = (x^3 – 3x^2 + 5x – 3)
area_base = (x^2 – 2)
height = Volume_prism / area_base
height = (x^3 – 3x^2 + 5x – 3) / (x^2 – 2)

Answer:
11/4 = 5/4
If you need 5/4 cups of sugar to make 20 cookies or in other words,
For 20 cookies you need 5/4 cups of sugar then
for 14 cookies you will need: 14 * (5/4)/20 = 7/8 cups of cookies
if you like a very sweet cookies then you can add a bit more sugar to make it 1 full cup of suger
