Answer 3

1. False (Every rational number is not a natural number)
2. True (Every natural number is also an integer)
3. False (Every irrational number is not an integer)
4. False (0.128128128... is a rational number, since it can be expressed as a repeating decimal)
5. Some examples of irrational numbers are: √2, π, e

Answer 4

A rational number is any number that can be written as a __________, where the denominator is not zero (a fraction). Examples include:
An irrational number is any number that cannot be written as a ____________. They fill in all the holes that exist between the set of rational numbers.

Answer 5

A rational number is any number that can be written as a ratio of two integers, where the denominator is not zero (a fraction). Examples include: 1/2, 3/4, -2/5.

An irrational number is any number that cannot be written as a fraction. They fill in all the holes that exist between the set of rational numbers. Examples include: √2, π, e.

Answer 6

1. Find the circumstance of a circle with a diameter (d) of 2.25 inches. Estimate the circumference to the hundredths place.
2. Find the area of a circle whose radius (r) is 7 inches. Use the formula A=Pir^2 and pi=3.14159. Estimate the area to the hundredths place.

Answer 7

1. The circumference (C) of a circle can be found using the formula C = πd, where d is the diameter. Given that the diameter is 2.25 inches, we can substitute it into the formula:
C = 3.14159 * 2.25
C ≈ 7.07 inches (rounded to the hundredths place)

2. The area (A) of a circle can be found using the formula A = πr^2, where r is the radius. Given that the radius is 7 inches, we can substitute it into the formula:
A = 3.14159 * (7)^2
A ≈ 153.94 square inches (rounded to the hundredths place)

Answer 8

Ok for both of the answers please list all the steps you did to get the answer

Answer 9

1. Finding the circumference of a circle:
- Given that the diameter is 2.25 inches.
- The formula for the circumference is C = πd, where d is the diameter.
- Substitute the given value of the diameter into the formula:
C = 3.14159 * 2.25
- Calculate the product:
C ≈ 7.07 inches (rounded to the hundredths place)

2. Finding the area of a circle:
- Given that the radius is 7 inches.
- The formula for the area is A = πr^2, where r is the radius.
- Substitute the given value of the radius into the formula:
A = 3.14159 * (7)^2
- Calculate the product:
A ≈ 153.94 square inches (rounded to the hundredths place)
