what is the capacity of the human testies
Answers
Answer:
The human testis is an ovoid mass that lies within the scrotum. The average testicular volume is 20 cc in healthy young men and decreases in elderly men. In Asian men, testes tend to be smaller. Normal longitudinal length of the testis is approximately 4.5 to 5.1 cm.
Explanation:
Let Sn = Sum of 'n' terms, then,
Sn = a + (a+d) + (a+2d) + (a+3d) +...+a+(n-1)d
Let | = last term, then,
Sn = a + (a+d) + (a+2d) + (a+3d) +...+ (1-3d) + (1 -2d) + (1 - d) + 1
reversing the order this gives:
Sn=1+ (1-d) + (1-2d) + (1-3d) +...+ (a+3d) + (a +2d) + (a + d) + a
Adding these last two equations gives,
2*Sna+l+ (a+l) + (a+l) + (a+l) +...+ (a+l) + (a+l) + (a+l) +a+l
2*Sn = (a+l) to n terms
2*Sn = = (a+l)*n
Sn = n/2*(a+l)
but I = a+(n-1)d, so substituting this gives:
Sn = n/2 (2a+(n-1)d)
