Area And Volume Exercise Form 3 May 2026

A cylinder has a radius of 3.5 cm and a height of 10 cm. What is its volume? (Use $\pi = \frac{22}{7}$) A) 110 cm$^3$ B) 385 cm$^3$ C) 120 cm$^3$ D) 350 cm$^3$

Whether you are preparing for your mid-year examinations or simply looking to sharpen your problem-solving skills, this guide covers everything you need to know. Below is a detailed breakdown of the Form 3 syllabus requirements, formulas, step-by-step examples, and a comprehensive students. Part 1: The Foundation – Two-Dimensional Shapes (Area) Before we can understand the space an object occupies (Volume), we must understand the space it covers on a flat surface (Area). In Form 3, the syllabus often expands beyond basic squares and circles to include composite shapes and sectors. 1. Composite Shapes A composite shape is simply a shape made up of two or more basic geometric figures (like rectangles, triangles, or circles). The strategy for these problems is always the same: Divide and Conquer. area and volume exercise form 3

If the side of a cube is doubled, the ratio of the new volume to the original volume is: A) 2:1 B) 4:1 C) 6:1 D) 8:1 Section B: Structured Questions (Intermediate) 4. A garden is in the shape of a rectangle, $20\text{ m}$ by $15\text{ m}$, with a semicircle of diameter $14\text{ m}$ attached to one of the shorter sides. Calculate the total area of the garden. (Use $\pi = \frac{22}{7}$) A cylinder has a radius of 3

$$V = \frac{1}{3} \pi r^2 h$$

Mathematics is often described as a language, and in Form 3, that language begins to describe the physical world with remarkable precision. For students transitioning from basic geometry to more complex spatial reasoning, the topic of Mensuration —specifically Area and Volume—stands as a critical milestone. Below is a detailed breakdown of the Form

$$\text{Volume} = \text{Area of Cross-Section} \times \text{Length (or Height)}$$
