## Formulas

$$\text{Volume of sphere }=\dfrac{4}{3} \pi r^{3} \text{, where }r \text{ is the radius}$$ $$\text{of the sphere.}$$
• AQA, Edexcel, and OCR will provide this formula in the exam in any relevant questions.
$$\text{Volume of cone }=\dfrac{1}{3} \pi r^{2} h\text{, where }r \text{ is the radius and}$$ $$h \text{ is the perpendicular height of the cone.}$$
• AQA, Edexcel, and OCR will provide this formula in the exam in any relevant questions.
$$\text{Volume of pyramid }=\dfrac{1}{3} \times \text{area of base} \times \text{height}$$
• Edexcel require you to learn this formula. AQA and OCR will provide this formula in the exam in any relevant questions.
