What is the formula of curved surface area of a cylinder?
The radius ‘r’ of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.
What is the difference between CSA and TSA of right circular cylinder?
The ratio between the curved surface area and the total surface area of a right circular cylinder is 1: 2. As we know that the curved surface area (C.S.A) of the right circular cylinder is 2πrh. And the total surface area (T.S.A) of the right circular cylinder is (2πrh+2πr2).
What is the formula of curved surface area and total surface area?
The curved surface area of a hemisphere(CSA) = ½ (curved surface area of a sphere) = ½ (4 π r2) = 2 π r2 , where “r” is the radius of the hemisphere. The total surface area of a hemisphere(TSA) = curved surface area + Base Area = 2 π r2 + π r2 = 3 π r2 , where “r” is the radius of the hemisphere.
What is the formula of total surface area of right circular cylinder?
Surface Area of Right Circular Cylinder Formula ⇒ Total Surface Area (TSA) = 2πrh + 2πr2 = 2πr(h+r) square units.
For which solid figure is the TSA same as its CSA?
Answer: Sphere is the answer for your question.
What is the difference between the TSA and TSA of cylinder?
The total surface area includes the area of the circular top and base, as well as the Curved Surface Area (CSA). Spreading LOVE. JK. Total surface area (TSA) of cylinder is the sum of the area of both circular bases and area of curved surface.
What is the formula to find the total surface area?
Variables:
| Surface Area Formula | Surface Area Meaning |
|---|---|
| SA=2B+Ph | Find the area of each face. Add up all areas. |
| SA=B+12sP | Find the area of each face. Add up all areas. |
| SA=2B+2πrh | Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height. |
What is the formula of total surface area?
Surface Area Formulas:
| Shape | Lateral Surface Area (LSA) | Total Surface Area (TSA) |
|---|---|---|
| Cuboid | 2h(l + b) | 2(lb + bh + lh) |
| Cube | 4a2 | 6a2 |
| Right Prism | Base perimeter × Height | LSA + 2 (area of one end) |
| Right Circular Cylinder | 2πrh | 2πr(r + h) |
Is curved or lateral surface area same?
The curved surface area is the area of the curved part in a solid shape, whereas, the lateral surface is the difference between the total surface area and the area of the base and top of the shape. It is to be noted that the curved surface area applies only to shapes that have curved surfaces.
