Answer:
A 1759 sq. units
Step-by-step explanation:
to find the surface area of a closed cylinder the formula is
2πr² + πdh
r = radius = 10
d = diameter = 10 + 10 = 20
2 x 3.14 x 10² + 3.14 x 20 x 18
628.3 + 1130.94 = 1759.24
ans = 1759
That would be a right-angled triangle.
Answer:
(-2, 6)
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
In this case, the center is (-2, 6).
The total number of ways the study can be selected is: 637065
Given,
Total number of women in a group= 13
Total number of men in a group = 12
Number of women chosen = 8
Number of men chosen = 8
∴ the total number of ways the study group can be selected = 13C₈ and 12C₈.
This in the form of combination factor = nCr
∴ nCr = n!/(n₋r)! r!
13C₈ = 13!/(13 ₋ 8)! 8!
= 13!/5!.8!
= 1287
12C₈ = 12!/(12₋8)! 8!
= 12!/5! 8!
= 495
Now multiply both the combinations of men and women
= 1287 × 495
= 637065
Hence the total number of ways the study group is selected is 637065
