Step-by-step explanation:
Perimeter of a Square = P = 4a
Where a = Length of the sides of a Square
Perimeter of a Rectangle = P = 2(l+b)
Where, l = Length ; b = Breadth
Area of a Square = A = a2
Where a = Length of the sides of a Square
Area of a Rectangle = A = l×b
Where, l = Length ; b = Breadth
Area of a Triangle = A = ½×b×h
Where, b = base of the triangle ; h = height of the triangle
Area of a Trapezoid = A = ½×(b1 + b2)×h
Where, b1 & b2 are the bases of the Trapezoid ; h = height of the Trapezoid
Area of a Circle = A = π×r2
Circumference of a Circle = A = 2πr
Where, r = Radius of the Circle
Surface Area of a Cube = S = 6a2
Where, a = Length of the sides of a Cube
Curved surface area of a Cylinder = 2πrh
Total surface area of a Cylinder = 2πr(r + h)
Volume of a Cylinder = V = πr2h
Where, r = Radius of the base of the Cylinder ; h = Height of the Cylinder
Curved surface area of a cone = πrl
Total surface area of a cone = πr(r+l) = πr[r+√(h2+r2)]
Volume of a Cone = V = ⅓×πr2h
Where, r = Radius of the base of the Cone, h = Height of the Cone
Surface Area of a Sphere = S = 4πr2
Volume of a Sphere = V = 4/3×πr3
Where, r = Radius of the Sphere
