Answer 1

Area of circle =
`\boxed{\sf{28.3 \: {in}^(2)}}`.

Step-by-step explanation:

Here's the required formula to find the area of circle :

`\twoheadrightarrow{\pmb{\sf{A_((Circle)) = \pi{r}^(2)}}}`

• A = Area
• π = 3.14
• r = radius

Substituting all the given values in the formula to find the area of circle :

`{\twoheadrightarrow{\sf{Area_((Circle)) = \pi{r}^(2)}}}`

`{\twoheadrightarrow{\sf{Area_((Circle)) = 3.14{(3)}^(2)}}}`

`{\twoheadrightarrow{\sf{Area_((Circle)) = 3.14{(3 * 3)}}}}`

`{\twoheadrightarrow{\sf{Area_((Circle)) = 3.14{(9)}}}}`

`{\twoheadrightarrow{\sf{Area_((Circle)) = 3.14 * 9}}}`

`{\twoheadrightarrow{\sf{Area_((Circle)) = 28.26}}}`

`{\twoheadrightarrow{\sf{Area_((Circle)) \approx 28.3}}}`

`\star{\boxed{\sf{\red{Area_((Circle)) \approx 28.3 \: {in}^(2)}}}}`

Hence, the area of circle is 28.3 in².

`\rule{300}{2.5}`

Answer 2

28.3 square inches

Explanation:

Use the area of a circle to determine its area:

`A=\pi r^2\\\\A=\pi(3)^2\\\\A=9\pi\\\\A=9(3.14)\\\\A=28.26\\\\A\approx28.3`

Therefore, the area of a circle with a radius of 3 inches is 28.3 square inches
