Answer:
About 527.79
Step-by-step explanation:
formula is A=2πrh+2πr^2
Answer: 18 units squared.
Step-by-step explanation:
Assuming you meant the height was 9 and the base was 4, or that the base was 9 and the height was four, simply do A = 1/2bh to get 18.
If you put $2130 into a fraction then you can tell
Answer:
Population standard deviation
Step-by-step explanation:
Mean value = 4 + 12 + 6 + 9 + 6 + 11 = 48 / 6 = 8 mean
Standard deviation with numbers close together in random samples show the numbers would be close to their average mean and would never show spread of data in lower range numbers
Range = 12 - 4 = 8 does not determine the ''spread'' for measures such as temperatures it shows the mean also as unintended.
Criteria must include lowest and highest temperature to reflect 100 years and so population standard in lower set data would reflect a reliable calculation.
