➡️ 37,680m² will be the curved surface area of the cylindrical tank.
Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm
We need to find the curved surface area
<u>We know that</u>,
➩ Curves surface area of a cylinder = 2πrh
r (radius) = 30cm.
h (height) = 200cm.
Therefore,
➩ Curves surface area of a cylinder:
➩ 2 × 3.14 × 30 × 200
➩ 2 × 18,840
➩ 37,680 m² ans.
Answer:
Solution,
base=1
perpendicular=?
hypotenuse=X
now,
using Pythagoras theorem,
x^2=p^2+b^2
or, x^2=p^2+1^2
or,p^2=x^2-1
or, p=√x^2-1
tan theta=perpendicular/ base
tan theta =√x^2-1/1
tan theta=√x^2-1
z=tan theta
z=√x^2-1
Hope this helps...
Good luck on your assignment..
