Pi Basics
This Greek letter is used to represent the ratio of a circle's circumference to its diameter.
Pi
This is the distance from the center of a circle to any point on its edge.
Radius
Pi is the ratio of a circle's circumference to this measurement.
Diameter
This is what you call a mathematician that takes over a ship.
A pi-rate
This is the circumference of a circle with a diameter of ten inches.
31.4 inches
To two decimal places, this is the numerical value of Pi.
3.14
If a circle has a diameter of 10 units, this is its circumference in terms of pi
10*(3.14)
Can Pi be expressed as a fraction of two integers?
No, because it is irrational
This is what a mathematician needs to fly his plane.
A Pi-lot's License
This is the circumference of a circle with a radius of four centimeters
25.12 centimeters
This is the date on which Pi Day is celebrated every year.
March 14th
This is the formula used to find the area of a circle
A=3.14(r)^2
What measurement of the circle do you get when calculating the square root of the quotient of the Area and Pi ?
The Radius
This is a mathematician's favorite dessert.
A Pi-napple Pi-e
This is the diameter of a circle with a circumference of 28.26 ft.
9 ft
Pi is classified as this type of number because its decimals never end and never settle into a repeating pattern.
Irrational
Find the area of a circle with a diameter of 6 units. (Use pi in your answer).
9(pi)
What is a rational number that is commonly used to espress Pi as a fraction?
22/7
This is what a mathematician does with their papers
A Pi-le of papers
This is the area of a circle with a diameter of four inches
12.56 square inches
This famous physicist, known for the theory of relativity, was born on Pi Day in 1879.
Albert Einstein.
If a circle’s radius is doubled, the area increases by this many times.
Four times.
Given the circumference, this is the formula to find the diameter
Circumference divided by pi
This is what you get when you divide a Jack-o-Lantern by its diameter.
A Pumpkin Pi-e
This is the area of a circle with a radius of five centimeters.
78.5 square centimeters
