Step 1

$R=6371km$

$A=\pi {r}^{2}=\pi \times (6371{)}^{2}$

$=127516118k{m}^{2}$

Step 2

11% of this area is under crop production.

$=\frac{11}{100}\times 127516118k{m}^{2}$

$=14026772.98k{m}^{2}$

Answer:

$=14.026\times {10}^{6}k{m}^{2}$

$R=6371km$

$A=\pi {r}^{2}=\pi \times (6371{)}^{2}$

$=127516118k{m}^{2}$

Step 2

11% of this area is under crop production.

$=\frac{11}{100}\times 127516118k{m}^{2}$
