Class 7th Maths (DPP) - Perimeter and Area of Circle

Description

🟢 Class 7 Maths – DPP Quiz: Perimeter and Area of Circle

📘 Quiz Description:

This Daily Practice Problems (DPP) Quiz is designed to test your understanding of the perimeter (circumference) and area of circles. The quiz includes a mix of direct formula-based questions and real-life word problems, helping you apply the concepts in practical situations.

📌 Important Information to Know Before the Quiz:

🔹 Basic Definitions:

• Radius (r): Distance from the center to the boundary of the circle.

• Diameter (d): The full width across the circle through the center.
  👉 $d = 2r$

🔹 Formulas:

• Perimeter / Circumference:

  $$C = 2\pi r \quad \text{or} \quad C = \pi d$$

• Area:

  $$A = \pi r^2$$

• Use $\pi = \frac{22}{7}$ or $3.14$ as given in the question.

🔹 Units:

• Circumference → in cm, m, etc.

• Area → in cm², m², etc.
