291.87 is a rational number.
Rational numbers can be expressed by a ratio of two integers; in other words, rational numbers can be written as a whole number, fraction, or percentage. An irrational number cannot be expressed this way. Examples of irrational numbers include √2 and π. Examples of rational numbers include 3/4, 48%, and 58.09.

Answer:
r =11 in
V = 968 pi in^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
The diameter is 22 so the radius is d/2 = 22/2 =11
V = pi * 11^2 * 8
V =968 pi
Mark ran 28.2 miles less than Cody, but Mark ran 12.4 miles, so Cody ran 40.6 miles.
miles Cody ran - miles Mark ran = 28.2
C - 12.4 = 28.2
C = 40.6 miles
Answer: area of fabric needed is 50.24 ft²
Step-by-step explanation:
The table in the shape of a circle has a diameter of 6 feet. This means that the diameter of the fabric that would just fit the table is 6 feet. Therefore, the diameter of the fabric needed to make a table cloth if it hangs 1 foot off the table would be 6 + 1 + 1 = 8 feet
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents radius of the circle.
π is a constant whose value is 3.14
Radius = diameter/2. Therefore
r = 8/2 = 4
Area of fabric = 3.14 × 4²
= 50.24 ft²
