it is required to make a closed cylindrical tank of 1m and base diameter 140cm from a metal sheet. How many square meters of the sheets are required for the same?
Answers
Answer:
hey see just take out curved surface area and then just add the area of two circular base. so u will get the area of metal sheet required
use, curved
area of metal sheet= surface area of
cylinder
+
ar. of 2 circular bases
Step-by-step explanation:
hope it helped u

Step-by-step explanation:
It is given that diameter of cylindrical vessel is 140 cm
Diameter = 140 cm
Therefore,
Radius of cylindrical vessel = 140/2 = 70 cm
Now,
Converting the cm in m we get,
70 cm = 70/100 = 0.7 m
And it is also given that height of cylindrical vessel is 1 m
Height = 1 m
★ According to question now,
Area of sheet required = TSA of cylinder
=> 2πr (r + h)
=> 2 × 22/7 × 0.7 (0.7 + 1)
=> 4.4 × 1.7
=> 7.48 m²
Therefore, Area required to make closed cylindrical vessel is 7.48 m².
