Volume (V) of a Square Pyramid= ⅓(Area of the base)(Height)
V of a Cone= ⅓(Area of the base)(Height)
V of a Sphere= 4/3∏r³
Area of a Circle= ∏r²
Circumference of a Circle= 2∏r
Area of a Triangle= [length of the base of the triangle(bottom line)]x[length of the height of the triangle(usually the straight line that is perpendicular to the base line so that it forms a 90⁰ line)] then divide that multiple by 2.
