Question

The perimeter of a circular field is 242m.the area of the field is

Answer 1

Answer:

Step-by-step explanation:

given data :-

Perimeter = 2 pye R

= 2*22/7*R = 242

R = 35

AREA OF CIRCLE =  PYE * R(2)

=22/7*35*35

=22*175

ANS:-  3850 cm sq

Answer 2

Answer:

$4658.5 {m}^{2}$

Step-by-step explanation:

Perimeter of circle is

$2\pi \: r$

hence put the given values

$2 \times \frac{22}{7} \times r = 242$

$242 = \frac{44}{7} \times r$

multiplying both side by 7/44, we get

$242 \times \frac{7}{44} = r$

$5.5 \times 7 = r$

$38.5 = r$

we get the value of radius of circle which is 38.5m

Area of circle is

$\pi {r}^{2}$

put the values,

$= \frac{22}{7} \: (38.5) {}^{2}$

$= \frac{22}{7} \times 1482.25$

$= 22 \times 211.75$

$= 4658.5m {}^{2}$

the area of circular field is 4658.5 square metre
