Answer 1

3850m^2 is the area of the circular field

Answer 2

Answer:

Rate × Circumference = Cost

24 × 2πr =5280

$r = \frac{5282}{24} \times \frac{7}{2 \times 32}$

= 35cm

$area \: of \: circle = { \gamma r}^{2} \\ = \frac{22}{7} \times 35 \times 5$

= 22×35×5

= 3850

cost = Rate × Area

=0.5 × 3850

= 1325
