Answer:

[tex]Area = 0.126 m^2[/tex]

Explanation:

Since the crossection of cylinder is of circular shape

so here the crossectional area will be given as

[tex]A = \pi r^2[/tex]

here we know that radius of the cylinder will be

[tex]R = 20 cm[/tex]

so in SI units it is given as

[tex]R = 0.20 m[/tex]

now we have

[tex]Area = \pi (0.20)^2[/tex]

[tex]Area = 0.126 m^2[/tex]
