i have know clue what it is
We call:

as the set of <span>the first 51 consecutive odd positive integers, so:
</span>

Where:





<span>and so on.
In mathematics, a sequence of numbers, such that the difference between two consecutive terms is constant, is called Arithmetic Progression, so:
3-1 = 2
5-3 = 2
7-5 = 2
9-7 = 2 and so on.
Then, the common difference is 2, thus:
</span>

<span>
Then:
</span>

<span>
So, we need to find the sum of the members of the finite series, which is called arithmetic series:
There is a formula for arithmetic series, namely:
</span>

<span>
Therefore, we need to find:
</span>
Given that

, then:

Thus:

Lastly:
Answer:
It's B

Because I randomly guessed and that was the answer.
The answer for your question is 2
Answer:
= 18.857 cm²
Step-by-step explanation:
The area of a segment is given by;
θ/360 × 2πr². where θ is the angle subtended by the arc to the center of the circle and r is the radius of the circle.
θ = 60, and r = 6
Therefore;
Area = 60/360 × 22/7 × 6²
= 18.857 cm²
