Explanation:
It is given that,
Part A :
Radius of the circle, [tex]r=6.1\times 10^4\ cm=6.1\times 10^6\ m[/tex]
The radius of the circle is given by :
[tex]A=\pi r^2[/tex]
Putting the value of r in above formula as :
[tex]A=\pi (6.1\times 10^6)^2[/tex]
[tex]A=1.16\times 10^{14}\ m^2[/tex]
or [tex]A=1.1\times 10^{14}\ m^2[/tex]
Part B :
Radius of the circle, [tex]r=6.1\times 10^4\ cm=6.1\times 10^6\ m[/tex]
As there is no uncertainty in the radius of the circle, so the calculation is as same as in part A.
The radius of the circle is given by :
[tex]A=\pi r^2[/tex]
Putting the value of r in above formula as :
[tex]A=\pi (6.1\times 10^6)^2[/tex]
[tex]A=1.16\times 10^{14}\ m^2[/tex]
or [tex]A=1\times 10^{14}\ m^2[/tex]
Hence, this is the required solution.
