Geometry and Measurements: Terms Related to the Circle

The video tutorial explains the basic geometry of a circle, including its center, radius, and circumference. It introduces the concept of circular sectors and uses a cheese analogy to make the concept relatable. The tutorial then demonstrates how to calculate the area of a circle by rearranging circular sectors into a parallelogram shape, leading to the formula πR².

What is the fixed point from which all points on a circle are equidistant called?

• Circumference

• Radius

• Center

• Diameter

Which formula is used to calculate the circumference of a circle?

• π R^2

• R^2

• 2 * π R

• π D

What is a circular sector?

• A full circle

• The diameter of a circle

• A part of a circle bound by two radii and a curve

• A line segment within a circle

How many equal pieces does the cheese pack contain in the shape of a circular sector?

• 6

• 10

• 4

• 8

What shape does the arrangement of circular sectors resemble, which helps in deriving the area of a circle?

• Triangle

• Square

• Rectangle

• Parallelogram
