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]
