विकल्प

• 140 cm²

• 154 cm²

• 616 cm²

• 88 cm²

Answer 1

The diameter of a circle is 14 cm. Its area is 154 cm².

Explanation:

The diameter of the circle is 14 cm,

So the radius r = `14/2` = 7 cm.

The area of a circle is given by the formula:

Area = πr² 

Using `π = 22/7`,

Area = `22/7` × 7 × 7

Area = 154 cm²

Hence, the area is 154 cm².
