Step-by-step explanation:
Given as :
The number of students in a class = x = 10
The number of students chosen by teacher to go to library = y = 2
Let The number of ways in which students were chosen = n ways
<u>Now, According to question</u>
So, number of ways in which students were chosen =
Or, n ways =
Or, n =
Or, n =
Or, n =
Or, n =
Or, n = 5 × 9
i.e n = 45
So, The number of ways in which students were chosen = n = 45 ways
Hence,The number of ways in which students were chosen is 45 ways . Answer
The answer is, C 400 loss.

The volume of the cone is a. 7,560 cm³.
Step-by-step explanation:
Step 1:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h).
Here we substitute π as 3.1415.
The volume of the cone
Step 2:
The diameter of the cone is 38 cm so the radius is 19 cm. The height is 20 cm.
The volume of the cone
The volume of the cone =
The volume of the cone is 7,560.5433 cm³ which if rounded off is equal to option a.
