please anyone tell area,of parellelogram ,really,rhombus,triangle, and curved surface area of cube public and cylinder
Answers
rhombus=1/2×product of diagnol
triangle=1/2b×h
csa of cube=4l^2
csa of cylinder =2×22/7×r×h
hi mate,
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
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Area of Rhombus Formula
Formulas to Calculate Area of Rhombus
Using Diagonals A = ½ × d1 × d2
Using Base and Height A = b × h
Using Trigonometry A = b2 × Sin(a)
i hope it helps you.
