Shape Formulas Flashcards
Area of a Square
A = a²
Volume of a Sphere
A = (4/3) • π • r³
where:
r = the radius
Surface Area of a Prism
SA = (2 • A) + (P • d)
where:
A = the area of the base shape
P = the perimeter of the base shape
d = the distance or height of the prism
Area of a Rectangle
A = w • h
Surface Area of a Sphere
SA = 4 • π • r²
where:
r = the radius
Area of a Ellipse
A = π • a • b
Area of a Parallelogram
A = b • h
Volume of a Cone
V = (1/3) • π • r² • h
where:
r = the radius
h = the height
Volume of a Pyramid
V = (1/3) • A • h
where:
A = the area of the base (a • b)
h = the height
Area of a Circle
A = π • r²
Surface Area of a Cone
SA = (π • r²) + π(r • s)
where:
r = the radius
s = the length of the side
Area of a Sector
A = ½ • r² • θ
Area of a Triangle
A = ½ • b • h
Volume of a Rectangular Prism
V = l • w • h
where:
l = the length
w = the width

A = ½ ( a + b) • h
Volume of a Prism
V = A • d
where:
A = the area of the base shape
d = the distance or height of the shape
Surface Area of a Cylinder
SA = (2 • π • r²) + (2 • π • r • h)
where:
r = the radius
h = the height
Surface Area of a Pyramid
SA = (½ • P • s) + A

P = the perimeter of the base
A = the area of the base
s = the side length
Volume of a Cylinder
V = π • r² • h
where:
r = the radius
h = the height
Surface Area of a Rectangular Prism
SA = 2(l • h) + 2(l • w) + 2(w • h)
where:
l = the length
w = the width
h = the height
