Question

If pi is 3.142 what is the area of a circle of radius 3.5 cm

Answer 1

38.4895cm²

Explanation:

The area=3.142×(3.5cm)²=38.4895cm²

Answer 2

The Area of circle is 34.49cm

Explanation:

⟼ Area of a circle =
`\sf \pi {r}^(2)`

where,

• π = 3.142
• r = radius = 3.5cm

⟼ Area = (3.142)(3.5)(3.5)

⟼ Area = (3.142)(12.25)

⟼ Area = 38.4895cm
