Answer 1

Answer:

The Area of circle is 34.49cm

Step-by-step 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

Answer 2

Answer:

38.4895cm²

Step-by-step explanation:

The area=3.142×(3.5cm)²=38.4895cm²
