Question

Determine the area of each circle need to use 3.14 for pi and round to the nearest tenth

Answer 1

Area of circle =
`\pi r^2`

`\pi=3.14 \\ r=28\ \text{in}`

`\pi r^2=3.14 * (28 \ \text{in})^2=2461.76 \ \text{in}^2`

Since the question ask to round to the nearest tenth, the answer is
`2461.8 \ \text{in}^2`

Answer 2

2461.8 in²

Explanation:

Area of a circle = r²π

Using r=28 and π=3.14:

Area = 28²×3.14 ≈ 2461.8 in² rounded to the nearest tenth (ans)
