Q
What is Pythagoras’ theorem and what is the formula?
A
Pythagoras’ theorem is used to calculate an edge distance of a ‘right angled’ triangle if two sides are known.
H² = a² + b²
2
Q
How to work out area of circumference of a circle?
A
C = 𝝅 (3.141) x d
3
Q
How to find area of a rectangle?
A
A = L x B
4
Q
How to find area of a triangle?
A
A = ½ b x h
Example:
Area(A) = 1/2 × a × c
= 1/2 × 5 × 3
= 7.5 cm2
5
Q
How to find an area of a circle?
A
A = 𝝅 x r²
5
Q
How to work out volume of a circle?
A
V = Area (A = 𝝅 x r²) x height
6
Q
How to work out volume of a rectangle?
A
V = Area (L x B) x height
