Circumference of Circles Applications

What is the relationship between the circumference of a circle and its diameter?

• Circumference = Diameter / π

• Circumference = 2 x Diameter

• Circumference = π x Diameter

• Circumference = Diameter + Radius

What is the significance of Pi in geometry?

• Pi is the value of 3.0

• Pi is only relevant in algebra, not geometry

• Pi is significant in geometry because it is the ratio of a circle's circumference to its diameter.

• Pi is used to calculate the area of a square

How is Pi used in real-world applications?

• Pi is used for predicting the weather

• Pi is used in various real-world applications such as calculating the circumference and area of circles, in engineering for structural analysis and design, and in physics for wave and oscillation calculations.

• Pi is used for social media algorithms

• Pi is used for cooking recipes
