Answer:
Dark life are those organisms invisible to the human eye and that can't be cultured. New organisms discovered due to advances in DNA analysis and computational power. Expanding the 'tree of life' may lead to many future innovations
Explanation:
Given:
A rectangular paper 14cm wide is rolled a long its width to form of cylinder with radius 20cm
To Find:
Area of rectangle sheet of paper
Solution:
As here we are given Length of the rectangular paper 14 cm. Radius of the cylinder is 20cm. So, we can find the Area of the rectangular sheet of paper.
\sf \mapsto Breadth \: of \: rectangle = area \: of \: circle↦Breadthofrectangle=areaofcircle
\sf \mapsto Breadth = 2πr↦Breadth=2πr
\sf \mapsto Breadth = 2 × \dfrac{22}{7} × 20↦Breadth=2×

22
×20
< /p > < p > \sf \mapsto Breadth = \dfrac{44 \times 20}{7}</p><p>↦Breadth=

44×20
\sf \mapsto Breadth = \dfrac{880}{7}↦Breadth=

880
Area of Rectangle = L × B
Where,
Length= 14 cm
Breadth = 88/7 cm
\sf \mapsto Area \: of \: Rectangle= 14 × \dfrac{880}{7}↦AreaofRectangle=14×
7
880
\sf \mapsto Area \: of \: Rectangle = 2 × 880↦AreaofRectangle=2×880
\sf \mapsto Area \: of \: rectangle = 1760 cm²↦Areaofrectangle=1760cm²
Hence,
Area of Rectangular sheet of paper is 1760 cm²
