The radius of a cylindrical tank is 14 m. And height 20 m. Is.Find the area of curvature of the cylindrical tank.(ii) Find the total surface area of a cylindrical tank.(iii) Find the volume of a cylindrical tank.
Answers
➺ Given :
- Radius of Cylinderal tank = 14cm
- Height of Cylinderal tank = 20cm
➺ To Find :
- Area of curvature of the cylindrical tank
- Total surface area of a cylindrical tank.
- Volume of a cylindrical tank.
➺ Solution :
(i) Curvature of Cylinderal tank
CSA of cylinder = 2πrh
CSA of cylinder = 2 × 22/7 × 14 × 20
CSA of cylinder = 44 × 2 × 20
CSA of cylinder = 88 × 20
CSA of cylinder = 1760cm²
(ii) Total surface area of cylinder
TSA of cylinder = 2πr (h + r)
TSA of cylinder = 2 × 22/7 × 14 (14 + 20)
TSA of cylinder = 44 × 2 × 34
TSA of cylinder = 88 × 34
TSA of cylinder = 2992cm²
(iii) Volume of cylinder
Volume of cylinder = πr²h
Volume of cylinder = 22/7 × 14 × 14 × 20
Volume of cylinder = 44 × 14 × 20
Volume of cylinder = 12320cm³
Therefore,
- CSA of cylinder is 1760cm²
- TSA of cylinder is 2992cm²
- Volume of cylinder is 12320cm³

Answer:
They differentiate into three main types: dermal, vascular, and ground tissue. ... Dermal tissue, for example, is a simple tissue that covers the outer surface of the plant and controls gas exchange. Vascular tissue is an example of a complex tissue, and is made of two specialized conducting tissues: xylem and phloem.They differentiate into three main types: dermal, vascular, and ground tissue. ...
