How do you find the circumference?

2*3.14R or 3.14D


How do you find the hypotenuse?

H square= A squared+ B squared


How do you find the height of a cylander?

H=V/pie R squared


Volume of a cylander

pie R squared H


How do you find the radius?

R squared= V/pie H


How do you find the SA of cones?

Convert 1 Litre into cm cubed

1000cm cubed= 1 litre
devide cm cubed by 1000 to get L and times by 1000 to get cm cubed

Circle Theorem 1

When an inscribed angle and a sector angle are subtended by the same chord, then the sector angle is twice the size of the inscribed angle


Circle Theorem 2

All inscribed angles subteneded by the same chord are equal (as long as they lie on the same side of the chord)


Circle Theorem 3

When a diameter subtends an inscribed angle, the measure of that angle is alwase 90


Circle Theorem 4

In a cyclic quadrilateral opposite angles are suplementery they add up to 180


Circle Theorem 5

A tangent line touches the circle at exactaly one point. a radius drawn to that point is perpendicular to the tangent
