Question

Find the area of each circle. Round to the nearest tenth. Use 3.14 or 22/7 for Pi. r = 7.1 m

Answer 1

158.3 m² (to nearest tenth)

Explanation:

Given

• 
  `\pi =3.14`
• 
  `r = 7.1`

Area of a circle =
`\pi r^2`

⇒ area = 3.14 x 7.1²

⇒ area = 158.2874

⇒ area = 158.3 m² (to nearest tenth)

Answer 2

Answer: [ 158.3 m² ]

area of circle: π(radius)²

Here the π shall be taken as 3.14 and radius given 7.1 m

Using the formula:

→ 3.14(radius)²

→ 3.14(7.1)²

→ 158.2874 m²

→ 158.3 m² _____rounded to nearest tenth
