V = (1/3) pi r^2 h where r is the radius of the circular base and h is the height of the cone.
V = (1/3) pi (15)^2 * 9
V = 675 pi
V = 2120,575 square cm (approx)
Answer:
9
Step-by-step explanation:
0.9 per cent of 1000 = 0.9(1000)/100 = 0.9(10) =9
B.................................................
The z-score is defined as the number of standard deviations above the mean. Its formula is z = (x - mean) / (standard deviation). So if we are given that this player's height has a z-score of 4.10 relative to others, this means that his height is 4.10 standard deviations above the mean.
