Answer:
CSA=1760cm²
TSA=1848cm²
Pls mark as brainliest!
Step-by-step explanation:
CSA of cylinder= 2πrh
=2×22/7×14/2×40
=2×22/7×7×40
=44×40
=1760cm²
TSA of cylinder = CSA of cylinder + 2(2πr)
= 1760+2×44
=1760+88
=1848cm²

Answer:
TSA = 2068cm² and CSA = 1760cm²
Step-by-step explanation:
Given : The diameter of Base is 14 cm and height is 40 cm of the cylinder.
To find : The curved surface area and the total surface area of cylinder ?
Solution :
The diameter of the base is d=14 cm
The radius of the base is r=7 cm.
The height of the cylinder is h=40 cm
The curved surface area of the cylinder is
CSA=2πrh
CSA=2 x 22/7 x 40
CSA=2 x 22 x 40
CSA=1760cm²
The total surface area of the cylinder is
TSA=2πrh + 2πr²
TSA=1760+2 x 22/7 x 7²
TSA=1760+2 x 22 x 7
TSA=1760+308
TSA=2068cm²
Therefore, TSA = 2068cm² and CSA = 1760cm²
Hope this helped
