Answer 2

$\sf{\huge{\underline{\orange{Given :-}}}}$

• The diameter of a circular garden is 9.8 m.

$\sf{\huge{\underline{\green{To\:Find :-}}}}$

• The area of a circular garden .

$\sf{\huge{\underline{ Solution :-}}}$

We, know the diameter of the circle is twice the length of radius.

Diameter of circle = 2 × radius.

According to the question,

The diameter of a circular garden is 9.8 m.

Diameter of circle = 2 × radius.

➝ 9.8 = 2 × radius.

➝ Radius = 9.8 / 2

➝ Radius = 4.9

The area of a circular garden = π r²

➝ 3.14 × 4.9 × 4.9

➝ 3.14 × 24.01

➝ 75.392 m²

Hence, The area of a circular garden is 75.392 m² .
