Surface Area and Volume Formulas

Length/Perimeter Formulas

• Circumference: c = \pi d or c = 2 \pi r
• Arc Length: l = \frac{\theta}{360} \times 2 \pi r

Area Formulas

• Square: A = s^2
• Rectangle: A = l \times b
• Triangle: A = \frac{1}{2} b h
• Parallelogram: A = b h
• Rhombus: A = \frac{1}{2} x y
• Kite: A = \frac{1}{2} x y
• Trapezium: A = \frac{1}{2} h (a + b)
• Circle: A = \pi r^2
• Sector: A = \frac{\theta}{360} \times \pi r^2

Surface Area Formulas

• Cylinder: SA = 2 \pi r^2 + 2 \pi r h
• Cone: SA = \pi r^2 + \pi r l
• Sphere: SA = 4 \pi r^2

Volume Formulas

• Cube: V = s^3
• Rectangular Prism: V = l \times b \times h
• Prism: V = A h
• Pyramid: V = \frac{1}{3} A h
• Cylinder: V = \pi r^2 h
• Cone: V = \frac{1}{3} \pi r^2 h
• Sphere: V = \frac{4}{3} \pi r^3

Pythagoras Theorem
