1,900,000,000 in scientific notion is
1.9 ×10^9
Answer:
12.56 square units
Step-by-step explanation:
The formula for circumference is
C = 2πr
Our circumference is 12.56. Using 3.14 for π, we have
12.56 = 2(3.14)r
12.56 = 6.28r
Divide both sides by 6.28:
12.56/6.28 = 6.28r/6.28
2 = r
The area of a circle is given by the formula
A = πr²
Using 3.14 for π and our radius of 2, we have
A = 3.14(2²) = 3.14(4) = 12.56.
Answer:
d) The data are quantitative because they consist of counts or measurements.
Step-by-step explanation:
The number of cases of flu treated at a certain hospital in different years consists in integer numbers (there cannot be 108.4 cases of flu treated in one year, just 107, 108, 109, etc).
Therefore the date are quantitative because the data consists of numbers which are counts of a certain number of individuals who were affected by the flu during different years.

Answer:
113.04
Step-by-step explanation:
The diameter is 12 so divide it by 2 to get the radius so its 6. Then, multiply the 6 with a 6 and multiply it by 3.14. Use the calculator and you get 113.04 to find the answer.
