• What is the ACR LENGTH equation?

  (X ÷360) × π × diameter
• What is the equation for AREA of a SECTOR?

  (X÷360) × π × radius²
• What equation is used to find the AREA of a CYLINDER?

  Area of cylinder=(2×π×r×h)+2×(π×r×2)
• What equation is used to find the AREA of a CIRCLE?

  Area of circle = πr² or π × radius²
• What equation is used to find the VOLUME of a PYRAMID/CONE?

  volume =(area of base × height) ÷ 3
• Equations linking mass, density and volume:

  •mass = density × volume

  •volume = mass ÷ density

  •density =mass ÷ volume
• Equations linking force, pressure and area:

  •force = pressure × area

  •area = force ÷ pressure

  •pressure = force ÷ area
• Equations linking distance, speed and time:

  •distance = speed × time

  •speed = distance ÷ time

  •time = distance ÷ speed
