Volume, Area, Surface Area, And Trig Flashcards
What is the equation for the area of a triangle?
Base x height / 2
What is the equation for the volume of a prism
Base x height / 2 x length
What is the equation for the area of a circle?
pie x radius^2
What is the equation for the volume of a cylinder?
pie x radius^2 x height
What is the equation for the area of a rectangle or square?
base x height
What is the equation for the volume of a cuboid?
base x height x length
What is the equation for the surface area of cylinder?
2 x pie x radius^2 top and bottom circle + 2 x pie x radius x height curved surface area
What are the three sides of a right triangle called?
- Hypotenuse
- Opposite
- Adjacent
How do you identify the hypotenuse line?
- The longest side
- Opposite the right angle
How do you identify the opposite line?
- Opposite the angle we’re looking for
or - Oppsite the angle we know
How do you identify the adjacent line?
- The one ‘left over’
- The side next to the right-angle and the angle involved in the question.
What are the three trig formula’s?
Sin(angle) = opp/hyp
Cos(angle) = adj/hyp
Tan(angle) = opp/adj
How do you convert from (mm) to (cm) to (m) to (km)
Distance
mm => cm (÷ 10)
cm => m (÷ 100)
m => km(÷ 1000)
How do you convert from (g) to (kg) to (t)?
weight
g => kg(÷ 1000)
kg => t(÷ 1000)
How do you convert from (ml) to (cl) to (l) volume
ml => cl(÷ 10)
cl => l(÷ 100)
