Answer 1

Correct Question :

The area of a circular garden whose diameter is 9.8m

• 57.46m²
• 75 64m²
• 75.46m²
• None of these

Answer :

[ Option c. 75.46m² ] is the correct answer.

Step-by-step explanation :

To Find,

• The area of circle

Solution,

Given that,

• Diameter of circle = 9.8m

FORMULA USED :-

• Area of circle = πr²

Where,

• r = Radius
• π = 22/7

So, first we need to find out the radius from the diameter of circle,

As we know that,

RADIUS = DIAMETER / 2, radius is,

➠ Radius = 9.8 / 2

➠ Radius = 4.9m

The radius of circle is 4.9m.

So, the Area of triangle is,

As we know that,

AREA = πr², the is

➠ Area = 22/7 × ( 4.9 )²

➠ Area = 22/7 × 4.9 × 4.9 .... dividing 4.9 and 7 with 7

➠ Area = 22 × 0.7 × 4.9

➠ Area = 75.46m²

Hence, the area of circle is 75.46m².
