please tell me where to use TSA CSA and volume
Answers
Answer:
csa is when the area of the figure is used ignoring the top n base
tsa includes area with base n top as well
volume is the total capacity

✔✔____________________✔✔
Trapezium :
Area = 1/2h(a+b)
Perimeter = Sum of all sides
✔✔____________________✔✔
Rhombus :
Area = d1 × d2/2
Perimeter = 4l
✔✔____________________✔✔
Quadrilateral
Area =1/2 × Diagonal × (Sum of offsets)
✔✔___________________✔✔
Kite :
Area = d1×d2/2
Perimeter = 2 × Sum on non-adjacent sides
✔✔____________________✔✔
Circle :
Area = πr^2 or πd^2/4
Circumference = 2πr or πd
Area of sector of a circle = (θπr^2 )/360
✔✔__________________✔✔
Frustum :
Curved surface area = πh(r1+r2)
Surface area = π( r12+ h(r1+r2) + r22)
✔✔____________________✔✔
Cube :
Volume: V = l3
Lateral surface area = 4a2
Surface Area: S = 6s2
Diagonal (d) = √3l
✔✔____________________✔✔
Cuboid :
Volume of cuboid: lbh
Total surface area = 2 (lb + bh + hl) or 6l2
Length of diagonal =√(l^2+b^2+h^2)
✔✔___________________✔✔
Right Circular Cylinder :
Volume of Cylinder = π r2 h
Lateral Surface Area (LSA or CSA) = 2π r h
Total Surface Area = TSA = 2 π r (r + h)
✔✔_______________✔✔
Volume of hollow cylinder = π r h(R2 – r2)
✔✔____________________✔✔
Right Circular cone :
Volume = 1/3 π r2h
Curved surface area: CSA= π r l
Total surface area = TSA = πr(r + l )
✔✔__________________✔✔
Sphere
Volume: V = 4/3 πr3
Surface Area: S = 4πr2
✔✔___________________✔✔
Hemisphere :
Volume = 2/3 π r3
Curved surface area(CSA) = 2 π r2
Total surface area = TSA = 3 π r2
✔✔___________________✔✔
Prism :
Volume = Base area x h
Lateral Surface area = perimeter of the base x h
✔✔_______________✔✔
Pyramid:
Volume of a right pyramid = (1/3) × area of the base × height.
Area of the lateral faces of a right pyramid = (1/2) × perimeter of the base x slant height.
Area of whole surface of a right pyramid = area of the lateral faces + area of the base.
✔✔____________________✔✔
Tetrahedron :
Area of its slant sides = 3a2√3/4
Area of its whole surface = √3a2
Volume of the tetrahedron = (√2/12) a 3
✔✔__________________✔✔
Regular Hexagon :
Area = 3√3 a2 / 2
Perimeter = 6a
✔✔__________________✔✔
Some other Formula :
Area of Pathway running across the middle of a rectangle = w(l+b-w)
Perimeter of Pathway around a rectangle field = 2(l+b+4w)
Area of Pathway around a rectangle field =2w(l+b+2w)
Perimeter of Pathway inside a rectangle field =2(l+b-4w)
Area of Pathway inside a rectangle field =2w(l+b-2w)
Area of four walls = 2h(l+b)
