Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.
They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if
, the triangle is right
- if
, the triangle is acute
- if
, the triangle is obtuse
The triangle is obtuse.
The answer is D.

Given:
Radius of the cylinder = 2 cm
Height of the cylinder = 3 cm
To find:
The surface area of the cylinder.
Solution:
The surface area of a cylinder is:
Where, r is the radius and h is the height of the cylinder.
Putting , we get
Therefore, the surface area of the cylinder is 62.8 square cm.
