Answer 1

Answer:

4073

Step-by-step explanation:

Pi*r^2

22/7×36×36

4073

Answer 2

Answer:226.285 $km^{2}$

Step-by-step explanation:

area of circle = 2$\pi$r

where r = radius of circle

therefore, area of this circle = 2 x 22/7 x 36

                                               =44/7 x 36

                                               =226.285 $km^{2}$
