Question

the diameter of a circular garden is 220 m Find the area of the garden take 2pie = 3.14

Answer 1

Diameter of the circular garden = 220m

Area = 2πr. = 2 × 3.14×220m = 1381.6m

Answer 2

SOLUTION :

The diameter of a circular garden = 220 m    (given)

To be found :-

The area of the garden

Radius of the circular garden = 220 ÷ 2

                                                 = 110 m

[ ∴ As radius of a circle = diameter ÷ 2 ]

Area of the circle = $\bf \pi r^{2}$ unit sq.

[ ∴ In which r is the radius of the circle ]

Area of the circular garden =  $\bf \pi r^{2}$ unit sq.

=  $\frac{ \bf{22} }{ \bf{7} } \times { \bf (110)}^{2}$ m sq.

= 38028.57 m sq.

Hence,

The area of the circular garden is 38028.57 m sq.
