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:
It can be solved in many forms
one by replacing each point to see which one satisfy the equation or by using quadratic formula
so the right answer is the fourth one
On the first spin, the probability that any specific number from 1 to nine inclusive is 1/9. On the second spin, the same value of probability applies. If the spinner is fair, the result from the first spin has no effect on the result of the second spin. therefore:
