• 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.
$$\text{Volume of pyramid }=\dfrac{1}{3} \times \text{area of base} \times \text{height}$$
