In the mathematical context, the perimeter is the line that surrounds a plane figure with two dimensions. Put, it is the measure of the space a shape will occupy. The perimeter of a circular figure is its circumference. What is the perimeter of other two dimensional shapes that you know? Attempt this quiz now!

Questions and Answers

1.

What mathematical operation is exclusively performed in obtaining the perimeter of a triangle?
- A.
  
  Addition
- B.
  
  Subtraction
- C.
  
  Multiplication
- D.
  
  Division
Correct Answer
A. Addition

Explanation
To obtain the perimeter of a triangle, we add the lengths of all three sides. This is because the perimeter represents the total distance around the triangle, and adding the lengths of the sides gives us this total distance. Therefore, addition is the mathematical operation exclusively performed in obtaining the perimeter of a triangle.

Who was the first to describe the perimeter of polygons?
- A.
  
  Pythagoras
- B.
  
  Plato
- C.
  
  Archimedes
- D.
  
  Aristotle
Correct Answer
C. Archimedes

Explanation
Archimedes was the first to describe the perimeter of polygons. He made significant contributions to mathematics and geometry, including the calculation of the circumference of a circle and the measurement of the perimeter of various polygons. Archimedes developed rigorous mathematical proofs and formulas, and his work laid the foundation for many mathematical concepts that are still used today.

Which of these refers to the perimeter of a circle?
- A.
  
  Circumference
- B.
  
  Radius
- C.
  
  Diameter
- D.
  
  Segment
Correct Answer
A. Circumference

Explanation
The correct answer is Circumference. The circumference of a circle refers to the distance around the outer edge of the circle. It can be calculated using the formula 2πr, where r is the radius of the circle. The circumference is an important measurement when dealing with circles as it helps in determining the length of arcs, areas, and other properties of circles.

What is the basis of isoperimetric problem?
- A.
  
  Perimeter
- B.
  
  Radius
- C.
  
  Length
- D.
  
  Area
Correct Answer
D. Area

Explanation
The basis of the isoperimetric problem is the area. The isoperimetric problem involves finding the shape with the maximum area for a given perimeter. This problem has been studied in mathematics for centuries and has applications in various fields such as physics and engineering. By focusing on the area, mathematicians aim to find the most efficient shape in terms of maximizing the enclosed space while keeping the perimeter constant.

Which of these is not needed to determine the perimeter of a circle?
- A.
  
  Radius
- B.
  
  Constant (Pi)
- C.
  
  Inscribed angle
- D.
  
  Diameter
Correct Answer
C. Inscribed angle

Explanation
The perimeter of a circle can be determined by using either the radius or the diameter. The constant Pi is also necessary as it represents the ratio of the circumference of a circle to its diameter. However, the inscribed angle is not needed to determine the perimeter of a circle. The inscribed angle refers to an angle formed by two chords of a circle that have a common endpoint on the circle. While the inscribed angle is a concept related to circles, it is not directly used to calculate the perimeter.

Which of these fields does not require the digits of constant Pi ?
- A.
  
  Algorithmics
- B.
  
  Computer science
- C.
  
  Geostatistics
- D.
  
  Mathematical analysis
Correct Answer
C. Geostatistics

Explanation
Geostatistics is the field that does not require the digits of the constant Pi. Geostatistics is a branch of statistics that deals with the analysis and interpretation of spatial data, particularly in the earth sciences. While Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter, it is not directly relevant or necessary in the study of geostatistics.

  Three
- B.
  
  Four
- C.

How many sides does a square have?
- A.
  
  Six sides
- B.
  
  Eight sides
- C.
  
  Nine sides
- D.
  
  Four sides
Correct Answer
D. Four sides

Explanation
A square has four sides because it is a quadrilateral with four equal sides. Each side of a square is also perpendicular to the adjacent sides, forming right angles. Therefore, a square has four sides.

What simple shape is characterized by a segment?
- A.
  
  Circle
- B.
  
  Triangle
- C.
  
  Square
- D.
  
  Hexagon
Correct Answer
A. Circle

Explanation
A circle is characterized by a segment because a segment is a part of a circle that is formed by a chord and its endpoints. A segment is a straight line that connects two points on the circumference of the circle, dividing it into two parts. Therefore, a circle is the simple shape that is characterized by a segment.

What parameter is most important for determining the perimeter of a circle?
- A.
  
  Diameter
- B.
  
  Radius
- C.
  
  Length
- D.
  
  Segment
Correct Answer
B. Radius

Explanation
The radius of a circle is the distance from the center of the circle to any point on its circumference. Since the perimeter of a circle is the distance around its outer edge, the radius is the most important parameter for determining the perimeter. The diameter is also related to the perimeter, as it is equal to twice the radius, but the radius is the primary parameter used in calculating the perimeter.
