The relationship between the symbol π and the word Pi is:

• π is the Greek letter for Pi, representing the mathematical constant.

• π and Pi are unrelated symbols.

• π is a symbol used in physics, while Pi is used in mathematics.

• π is the symbol for the number 3, while Pi is the symbol for the number 4.

The value of Pi comes from what ratio?

• Circumference to diameter of a circle

• Diameter to radius of a circle

• Area to radius of a circle

• Radius to circumference of a circle

Pi is called a mathematical constant because:

• it is a variable that changes with different circles.

• it is a fixed value that represents the ratio of a circle's circumference to its diameter.

• it is only used in geometry.

• it is a number that can be expressed as a simple fraction.

Pi continues infinitely because:

• it is a rational number.

• it is an irrational number.

• it is a whole number.

• it is a prime number.

Pi is an irrational number because:

• it can be expressed as a fraction.

• it has a finite decimal expansion.

• it cannot be expressed as a fraction and has an infinite, non-repeating decimal expansion.

• it is a whole number.

How many digits of Pi are known?

• 10 trillion

• 5 trillion

• 1 trillion

• 100 billion

The symbol π was first used by which mathematicians?

• Leonhard Euler

• Isaac Newton

• William Jones

• Carl Friedrich Gauss

Pi Day is celebrated on March 14 because:

• it is the birthday of a famous mathematician.

• it represents the first three digits of Pi (3.14).

• it is the day when Pi was discovered.

• it is a national holiday in the USA.

For how many years has Pi Day been celebrated?

• 10 years

• 20 years

• 30 years

• 40 years

March 14 is also whose birthday?

• Albert Einstein

• Isaac Newton

• Galileo Galilei

• Nikola Tesla
